Sky-Watcher EQ6-R

Sky-Watcher EQ6-R Pro Review

|Equipment|35 Comments

The Sky-Watcher EQ6-R Pro is a computerized equatorial telescope mount with GoTo capabilities. This equatorial (EQ) mount is capable of providing precise, accurate tracking of the night sky, and is suitable for long-exposure astrophotography. 

The core specifications of this equatorial mount include having a built-in ST-4 autoguider port, a payload capacity of 44 pounds, and a SynScan computer hand controller with an extensive database of objects. 

I have been using the Sky-Watcher EQ6-R Pro telescope mount since October 2018, and have used it to capture several deep sky images of nebulae, galaxies, and star clusters in space. In this post, I’ll share some of my favorite features of this EQ mount that I have experienced over several imaging sessions in the backyard.

Sky-Watcher EQ6-R Pro Review

Before we dive into some of the interesting features you may not have known about, here is an overview of exactly what the “EQ6” is capable of. As a preface, it’s worth noting that I use this mount for astrophotography exclusively, and I am in the northern hemisphere.

For those in the southern hemisphere, the process is very similar all around, aside from polar aligning the mount with the south celestial pole (SCP).

Before stepping up to the EQ6-R, I used a number of intermediate level astrophotography mounts, including the slightly smaller HEQ5 Pro SynScan model. 

Sky-Watcher EQ6-R Pro

The Basics

The EQ6-R Pro includes a SynScan hand controller with an LCD display that gives you control it’s features and basic functions. The left and right keys on the keypad control the Right Ascension (RA) axis, while the up and down arrows are used to control the Declination (DEC) axis. 

You can control the slew speed by selecting the RATE shortcut button (2) on the keypad, as it is useful to make large movements at a high speed, and subtle adjustments using a slow speed. The Sky-Watcher EQ6-R Pro has 10 slew speeds for complete control over the movement of each axis. 

Before powering up the EQ6-R, your telescope should be in the home position. This means that the EQ head is leveled on the tripod, and the RA axis is pointed towards the north celestial pole (NCP). The counterweight should be at its lowest position, and the telescope should be pointing towards the NCP.  You can then turn on the mount and select the operation mode. 

For those interested in astrophotography, you will only ever want to use the mount in EQ mode. 

Iris Nebula

With the RA and DEC clutches locked, and counterweight(s) attached, you can mount your telescope on top of the EQ head. This is accomplished by fastening the mounting plate of your telescope to the saddle, which accepts both D and V-style mounting plates.

If you are looking for a nice upgrade, the Dual EQ6R-Pro XL collar was redesigned to fit the EQ6R-Pro and features two large locking hand knobs and spring-loaded jaws.

Getting Started

Once the SynScan system has initialized, you can enter in the geographic coordinates of your observing site.

This involves entering the latitude and longitude coordinates of your current location using the cursor on the LCD display and the keypad. Then, you will enter your current time zone, which for me, happens to be UTC -4 in southern Ontario. 

You can also enter in your current elevation, which is used for atmospheric refraction compensation (generally, the higher your elevation, the better). Next is setting the current date and time, and whether you are currently on daylight savings time.  

Once all of these important details have been entered (so the mount understands what is available in the sky from your location), you reach the mount alignment process, with the “Begin Alignment” dialog served up on the LCD screen. 

SynScan Hand Controller

Use the “Park” Feature

This simple, yet useful feature automatically aligns your telescope mount in both axes at the beginning of your imaging session. It is not exclusive to the EQ6-R Pro, yet it is easy to miss if you don’t follow the instructions in the manual on your first few runs. 

This feature is located under the “Utility Function” menu and asks you to turn off the mount after the park position has been confirmed. The next time you turn the mount on, you will see a dialog on the LCD display asking if you would like to start from the park position.

This is a handy feature that I did not personally take advantage of for the first few months of ownership with the mount. It is nice to confirm the home position when setting up, especially before beginning your polar alignment process.

The EQ6-R is Easy to Polar Align

Whether you use the built-in polar scope with the illuminated reticle or use a QHY PoleMaster device, polar aligning the EQ6-R is a breeze. 

This largely due to the fact that the EQ6-6 includes large, Alt/Az adjustment bolts with comfortable handles. Fine-tuning the polar axis of this equatorial telescope mount is possible thanks to these convenient controls.

The built-in polar finder scope with an illuminated reticle allows you to accurately polar align the mount without the need for additional software or accessories. You can either use a third-party mobile app like “Polar Finder” to find out the current position of Polaris, or simply use the information displayed on the SynScan hand controller. 

The SynScan hand controller displays the position of Polaris in polar scopes field of view (FOV). You need to imagine that the large circle in the FOV of the polar scope as a clock’s face with 12:00 sitting at the top.

Then, it’s simply a matter of adjusting the Alt/Az bolts of the mount to place Polaris in the “HH:MM” position provided.

Using a PoleMaster with the EQ6-R

If you don’t like getting underneath the polar scope for a real-time view of the NCP or SCP, the QHY PoleMaster is a great option. This electronic polar scope uses a small camera to display the region surrounding the north (or south) celestial pole. 

Using the live feed through the camera, you can fine-tune your Alt/Az adjustments in a very precise manner. The PoleMaster requires the appropriate adapter (this is the one you need) to fasten it to the polar axis.

You Can Improve the Alignment Accuracy

Before running a star alignment routine, make sure that your telescope is well balanced, and that there are no loose cables that could get caught and snag on the mount. 

The alignment routine involves choosing a bright, named star from the database and centering it in your telescope eyepiece or camera. The LCD screen displays “Choose 1st Star”, at which point you can cycle through the list to find a star that is not blocked by any obstructions from your location and press enter.

A word of caution here, once you hit enter, the mount will start to slew to the object immediately. 

From here, it’s a matter of using the arrow buttons on the keypad to center the star. Remember, you can change the slew speed at any time by pushing the “Rate” button and setting the value higher or lower. It is often useful to leverage a finder scope on your telescope when slewing to your first alignment star, as it has a much wider field of view than your primary telescope and makes finding the first star easier. 

When running through a star alignment routine, it is important to consistently center the alignment star in the eyepiece or camera’s FOV. It is beneficial to use a reticle eyepiece with a small FOV. Personally, I use the camera’s FOV and center the star on my DSLR display screen (with grid-enabled), or with a cross-hair overlay in my camera control software (Astro Photography Tool).

You can run a 1,2, or 3-star alignment to improve the pointing accuracy of the telescope. This is very important when it comes to photographing deep-sky objects that are nearly invisible until a long exposure image is collected.

Avoid Errors due to Mechanical Backlash

You can improve your alignment accuracy by avoiding errors due to mechanical backlash. Backlash is present in all equatorial telescope mounts and does not affect your observing enjoyment, or your long exposure images when autoguiding is employed.

To avoid introducing alignment error caused by backlash, center the alignment star ending with UP and RIGHT directions from the keypad. If you overshoot the star using this method, use LEFT and DOWN to bring the star back down the FOV and try again.

Computerized Telescope Mount

The Stepper Motors are Quiet

If you haven’t used this particular mount first hand, you may be wondering what the EQ6-R sounds like while it is slewing. I have heard many astrophotography mounts over the years, and this one is impressively quiet. 

This mount uses stepper motors with a 1.8° step angle and 64 micro steps driven. This technical design aspect results in a quieter mount than on using servo motors.

This means that even at the maximum slew speed (9X), the mount emits a modest hum that will not wake up your neighbors. While the telescope mount is tracking, it is completely silent. It’s only when you move the RA or DEC axis at top speed that you hear a noise.

Compared to other equatorial telescope mounts I have used, the audible sound the EQ6-R Pro makes is more than acceptable. When you are partaking in a hobby that takes place (alone) outside at night, avoiding loud or unusual noises when possible is always a good idea.

In contrast, the Celestron CGX-L computerized mount is noticeably loud while slewing at top speed. If this mount is being used in a closed observatory, it’s not an issue. However, I set up my equipment in a city neighborhood backyard. Depending on the time of night, I hesitate slewing to a new target because of this trait. 

The Autoguiding Performance is Impressive

The Sky-Watcher EQ6-R Pro delivers impressive results when the built-in autoguider port is leveraged. Over the years I have maximized the tracking capabilities of my astrophotography mounts by using an auxiliary guide scope and camera to autoguide using free software called PHD2 guiding

The EQ6-R Pro allows you to set change the default auto guide speed of the mount of 0.5X to 0.75X or 1.0X in the setup menu.  

I have experimented using a guiding rate of 1.0X and saw little improvement to my guiding graph in PHD2 guiding over the default speed of 0.5X. The point is, you have the option of adjusting this setting if the need calls for it, and it’s a feature I’ve only recently tapped into on the EQ6-R Pro.

For a real-life example of the autoguiding performance, you can expect with this mount, have a look at the screenshot below. The guiding graph shows that my total RMS error is 0.63″. Generally, a total RMS error of under 1-second means that you can expect pinpoint stars in your long exposure images.

The Mount is Heavier Than it Looks

When it comes to equatorial mounts for astrophotography, being heavy is a good thing. However, I think some people that receive their EQ6-R for the first time may be a little surprised at how heavy the EQ6-R actually is (I was).

The weight of the EQ head is 38 lbs on its own, and the tripod adds another 16.5 lbs. Add in two 11-lb counterweights, and you’ve got a telescope rig that weighs 76.6 pounds and is not going anywhere for a while.

Luckily, the EQ head includes a useful carry handle that I have certainly put to good use. Also, the supplied counterweight bar is retractable, which makes transporting the mount out the door of my garage a little easier. 

mount specifications

I used to carry my Sky-Watcher HEQ5 Pro SynScan around the yard with the telescope and counterweight attached. It was heavy and awkward, but manageable.

This is not possible with the EQ6-R, which is understandable considering the increased payload capacity (44-lbs) of the mount. To transport the Sky-Watcher EQ6-R from my detached garage to the yard, I must remove the counterweights and the telescope first.

It’s possible to lift the tripod with the EQ head attached (54.5 lbs), but this is likely too heavy for most folks. The good news is, this heavy profile means that accidentally bumping the polar alignment out of position by kicking a tripod leg is unlikely. Smaller, ultra-portable mounts like the iOptron SkyGuider Pro do not share this quality. 

You Don’t Need to “Mod” the Mount

If you’re a tinkerer, I get it. It may be tempting to you to open up the EQ mount head and take a look. I would advise against this personally, as you may do more harm than good.

I’ve seen a number of posts and videos discussing “belt-mods” and “hyper-tuning” Sky-Watcher NEQ6 and EQ6-R mounts. Personally, I wouldn’t recommend opening up the mount in hopes of tweaking performance, even if the underlying mechanics are straightforward to you.

In my experience, the Sky-Watcher EQ6-R can track accurately for 10-minute exposures (or longer) without any re-greasing or modifications to the worm gears when autoguiding is leveraged.

I suggest spending the time to get your balance and polar alignment spot-on before blaming the mount for bad tracking. It’s easy to get caught up in scrutinizing the mechanical backlash and periodic error present in the mount.

If you do dive into these advanced adjustments, you better be mechanically minded and ready to invest a “minimum of four hours” for a typical belt modification.

The SynScan Hand Controller gives you Extensive Options

The included SynScan hand controller includes an impressive 42,000+ object database, with almost every possible target you could ever want to observe or photograph.

The Messier object list gets a lot of use for amateur astronomers in the Northern Hemisphere, while the NGC catalog is great for pointing the telescope at more obscure nebulae and star clusters.

The database also includes IC and Caldwell catalogs, which covers most of the noteworthy subjects in the night sky. I only wish the database included the Sharpless catalog, for items such as the Tulip Nebula with no alternative designation.

To slew to these objects, it may be better to control the EQ6-R using your PC using a supplementary PC-Link cable along with the appropriate ASCOM drivers and software.

I use the hand controller to align and center my target. After a quick polar alignment routine using the QHY PoleMaster, the pointing accuracy of the mount is spot-on using just a 1-star alignment.

After you’re aligned and ready to observe or image an object in space, you can start by choosing a target using the “OBJECT” shortcut key, which contains the following object list:

  • Named Stars
  • Solar System
  • NGC Catalog
  • IC Catalog
  • Messier Catalog
  • Caldwell Catalog
  • SAO Catalog
  • Double Stars
  • Variable Stars
  • User Object
  • Deep Sky Tour

The deep sky tour is a very cool feature for visual observation sessions. Imagine a star party or public outreach event where you want to have the best list of targets at the ready.

This feature generates a list of the most famous deep-sky objects that appear in the current night sky overhead. You simply go through the list and pick them off one by one.

The Periodic Error Correction (PEC) Feature

Periodic tracking error is present in all equatorial telescope mounts, and is due to the design of the internal gears. The Sky-Watcher EQ6-R includes a periodic error correction (PEC) function to help correct this.

The PEC training procedure requires that you first polar align and star align the telescope mount. Then, slew to a star close to the celestial equator, and center it in the telescope eyepiece or imaging camera.

Then, navigate to the Utility Function > PEC Training mode and press enter. From here you can select the speed you would like to use for PEC training. The Sky-Watcher SynScan manual suggests using 0.125X sidereal rate for wider FOV telescopes such as the Esprit 100 ED APO.

After selecting the speed using the “1” or “2” keys, the screen will then start to display the elapsed time of the PEC training routine. Now, your job is to keep the star centered in the FOV using the left and right direction keys on the hand controller.

Once the PEC training routine has completed, the elapsed time will stop. Noe, you can select “PEC+Sidereal” as a tracking speed in the Setup menu. It is recommended to wait for at least one PEC training reply cycle to complete before you start taking your images.

Sky-Watcher SynScan Specifications

  • Object Catalog: Messier Catalog, NGC, SAO, Caldwell, Double Star, Variable Star, Named Star, Planets
  • Pointing Accuracy: Up to 5 arc-minutes RMS

Power Supply for the Sky-Watcher EQ6-R Pro

As one Cloudy Nights forum member put it, the Sky-Watcher EQ6-R Pro can get “cranky” if the right power supply is not used. I have experienced this issue myself, when I used an AC to DC power adapter that did not provide a minimum 4 amps of power.

These days, I use a 12V AC/DC adapter with 6 amps to power the EQ6-R when plugged in at home. Here is a picture of the exact AC/DC adapter I use with the EQ6-R, and here is a link to it on Amazon. Others have found the Pyramid PS9KX 5 Amp power supply to work well with this mount.

Final Thoughts

As you may have noticed, there is a lot to cover when discussing all of the features of the Sky-Watcher EQ6-R Pro SynScan computerized telescope mount. The very first night I used the EQ6-R, I captured one of my favorite astrophotography images to date, and I knew I was in a for a long relationship with this mount. 

A reliable equatorial mount is the foundation of every great deep sky astrophotography kit, and the EQ6-R is a worthy investment for those looking for a stable, long-term solution for long-exposure imaging.

From my early days with the HEQ5 Pro to my latest session in the backyard with the EQ6, I’ve been extremely satisfied with the user experience and performance of Sky-Watcher’s affordable equatorial telescope mounts.

The Foundation of Every Great Deep Sky Astrophotography Rig

|Equipment|22 Comments

Over the past 8 years, I’ve had the pleasure of using a number of telescope mounts for astrophotography. Some of them were substantial imaging platforms that included features such as autoguiding and periodic error correction (PEC), while others simply tracked the night sky at sidereal rate in a compact and portable package.

The payload capacity and features of the telescope mounts available today vary, but their level of importance in regards to your overall astrophotography goals remain constant. After many years of enjoying backyard deep-sky astrophotography, I can safely tell you that your telescope mount will be the single most important piece of your equipment.

telescope mounts

Equatorial telescope mounts come in many shapes and sizes (and colors)

My latest adventures in the backyard have reminded me of the positive impact the right telescope mount can have on your overall imaging experience. In this hobby, the difference between a night of frustration and one of jubilation is often tied to the user experience your equipment provides.

Choosing a telescope mount for astrophotography is one of the biggest decisions you’ll have to make in this hobby. With steep price tags and overlapping features between models, it can be hard to make the right decision. So leverage my years of trial and error in this addictive and rewarding hobby we call astrophotography before you pull the trigger on a new mount.

In this post, I’ll share what’s worked for me in the past, and my early results using a new intermediate-level telescope mount for astrophotography, the Sky-Watcher EQ6-R Pro. I’ll include the images I’ve captured using this mount so far and specific performance indicators such as my autoguiding graph in PHD2 guiding.

The Most Important Piece of every Astrophotography Setup

I think we can all agree, that if the Earth didn’t rotate, deep sky astrophotography would be a heck of a lot easier. Compensating for the apparent movement of the night sky is why amateur astrophotographers require an equatorial mount to capture images through their telescopes.

However, even a small error in tracking accuracy will be “exposed” in a long exposure deep-sky image. In terms of astrophotography, the higher in magnification you go with your telescope, the more pronounced this error will be.

This is one of several reasons I continuously recommend a wide-field refractor telescope for beginners, as they are the most forgiving in this regard. They offer some of the lowest magnification views of the night sky, which is actually a benefit for many deep-sky photography targets.

telescope mount for astrophotography

My previous astrophotography mounts included the Celestron CG-5, Sky-Watcher HEQ5 and iOptron CEM60

Telescopes with a higher magnification may reveal any drift occurring from the mount. It will show itself in the form of elongated stars. An inaccurate polar alignment or periodic error in the right ascension axis may be the culprit.

But enough about the subtleties and joy of troubleshooting tracking issues, for now. The bottom line is, your telescope mount is the foundation of your astrophotography experience and can make or break the quality and consistency of your images.

An equatorial telescope mount that provides you with consistent, reliable results night in and night out can make the difference between a lifelong hobby, and a rotten experience that’s discouraging enough to make you want to put the telescope away for good.

I’d rather you take the first road mentioned, and that is the mindset behind this article.

Plan for Future Configurations

When it comes to selecting your first telescope mount for astrophotography (or upgrading your existing mount), I’d like to offer the following advice. Plan for the future. This isn’t groundbreaking advice and I am sure you’ve heard this mentioned before – but it’s the “why” that I am here to explain.

It’s easy to get caught up in the purchase of a new telescope for astrophotography and think “this is the telescope for me, the only one I’ll ever need”. This is how I felt about my Explore Scientific ED102 refractor. At the time, it was at the far reaches of my budget, and I believed that it would be the last telescope I’d ever buy.

I thought, as long as my current telescope mount could carry this 7-lb carbon fiber triplet, with my camera and accessories attached, I’d never need to upgrade. The truth is, I could have stuck with this combination for life – but then AstroBackyard happened.

What I mean by my previous statement is, I knew my YouTube channel and blog would get pretty stagnant if I continued to talk about the same equipment over and over again. Thankfully, I met Steve from Ontario Telescope in 2016, and the rest is history. (You can listen to Steve and talk astrophotography on the AstroBackyard Podcast).

Leave Room to Grow

For the first 5 years of my DSLR astrophotography experience, I was more than happy with using an 80mm refractor and a beginner level telescope mount. If you own a compact telescope (like the William Optics Z61 pictured below) that does not require a heavy-duty mount, you may never feel the need to upgrade. It means that have better self-control than most.

The problem is, deep-sky astrophotography is an addiction – and upgrading to a larger telescope down the road is a common occurrence. The setup pictured below includes the highly portable iOptron SkyGuider Pro, which is not only an incredible beginner-friendly mount – but a real performer.

It’s also a gateway mount” into the realm of deep-sky astrophotography I currently live in.

iOptron SkyGuider Pro

Suddenly, the 11-lb payload capacity of your modest mount can no longer produce sharp images with your new telescope because it’s too heavy. That doesn’t mean you won’t use it anymore, but it will limit the types of telescopes you can mount to it.

On the other hand, if you “over-mount” from the beginning, you’ll have more than enough stability to run your current telescope kit, with lots of room to grow in the future.

Here’s a statement you may have heard before, that I have found to be true. For deep-sky astrophotography, you’ll want your telescope mount to have a payload capacity that is double the weight of your imaging gear. This may seem a little excessive, and there is certainly some wiggle room here. But in general, it’s a great rule of thumb.

My Telescope Mount Timeline

Year Brand Model Payload Capacity
2010 Celestron Advanced Series CG-5 25 lbs
2014 Sky-Watcher HEQ5 Pro SynScan GoTo 30 lbs
2017 iOptron SkyGuider Pro Camera Mount 11 lbs
2017 iOptron SkyTracker Pro Camera Mount 6.5 lbs
2017 iOptron CEM60 Center-Balanced Equatorial Mount 60 lbs
2018 Sky-Watcher EQ6-R Pro Computerized GoTo Mount 44 lbs
2019 Celestron CGX-L 75 lbs

I’ll be the first to admit that I may be a little biased towards Sky-Watcher mounts, but for good reason. Although I have spent some serious time with iOptron and Celestron mounts in the past, none compare to the mileage I’ve put on my Sky-Watcher HEQ5 Pro. I love this old mount, rusty counterweights and all.

It’s been repeatedly packed and unpacked from closets, garages, and trunks (and has the battle scars to prove it). It’s been everywhere from the dark skies of Cherry Springs to the dark corners of our basement apartment closet. How could I not hold a special place in my heart for a mount that has been the cornerstone of my hobby for so many years?

The Sky-Watcher EQ6-R Pro Computerized GoTo Telescope Mount

For this reason, I got a little extra excited when Sky-Watcher reached out to me about a snow-white EQ6-R Pro. I believe my years of use with the HEQ5 accelerated my comfort level and enjoyment with the EQ6-R Pro early on. The SynScan hand controller system and the overall user experience of the mount all felt very familiar to me.

Sky-Watcher EQ6-R First Impressions (Video)

Rudy kept a close eye on the giant boxes with “new smells” I opened on my backyard patio. In total, the shipment weighed 90 lbs. It was covered in “team-lift” stickers to avoid a lawsuit. My team consisted of myself, adrenaline, and black Labrador retriever. The feeling of unboxing a new piece of astrophotography gear (especially a new mount) is an unforgettable experience. I didn’t film an unboxing video this time, but I did snap a few pictures.

Setting up the Sky-Watcher EQ6-R Pro Telescope Mount

The first and most obvious thing I noticed while unpacking the Sky-Watcher EQ6-Pro was how heavy it was. In the world of equatorial mounts, that’s a very good thing. Stability is everything when your tracking objects that live in deep space, and the EQ6-R is rock-solid. Secondly, I noticed the green accents on the setting circles that match the new branding of the Esprit 100ED – this is less important but appreciated nonetheless.

Seeing as how the EQ6-R is the HEQ5’s new and improved big brother, I was absolutely smitten with delight unpacking and setting it up. For lack of a better analogy, it’s like going from an old Toyota Corolla to a RAV4😉

Upcoming Sky-Watcher EQ6-R Pro Review

A complete review of the Sky-Watcher EQ6-R Pro will take time and more experience to build properly. At this stage, I simply want to share my first impressions with the mount. I will say this, I can’t remember the last time I was able to unbox a piece of astrophotography gear and produce an amazing deep sky image on the same day.

The fact that this is an advanced equatorial telescope mount, makes this statement even more impressive. If my early experiences with the EQ6-R are any indication of what I can expect (2 nights in), this should be a lot of fun.

Deep Sky Astrophotography with the EQ6-R

The Sky-Watcher EQ6-R arrived at my door on Friday, and it sat in the dining room hallway until Saturday. With clear skies in the forecast for Saturday night, I was given the rare opportunity to try out a new piece of gear right away. (Longtime amateur astronomers and photographers know that new equipment is usually met with a week of cloud cover, at a minimum).

Everything was neatly packed in the box with a custom foam insert that cradled the head of the EQ6-R mount. I’ll keep this packaging for transporting the mount in the future, to take advantage of this custom fitted padding. The foam can be used in a large carry-case when I decide to upgrade from a cardboard box.

Over the years, I’ve seen a wide variety of instruction manuals and spec sheets that accompany new astro-gear. Some have been nothing more than a vague description of the product with poor spelling – and a link to a website for more info. This was not the case with the Sky-Watcher EQ6-R. The manual is an in-depth, premium resource, complete with detailed diagrams and well-written dialogue. Sometimes, it’s the little things that make the difference.

After locking the mount head into place on the tripod and securing the spreader/eyepiece tray, I corrected the latitude of the polar axis for my location. The dial is easy to read and responsive. It wasn’t much of an adjustment from the default position of about 45 degrees to 43 here in Ontario, Canada.

Alt-Az Bolt Upgrades

It’s impossible to ignore the impressive upgrades made to the alt-az bolts on the EQ6-R. Going from the rather dinky bolts on my old HEQ5 to the robust handles on the EQ6-R was quite the upgrade. The focus put into this seemingly underrated update is surely the result of user feedback over the years, and much appreciated from someone who’s spent a lot of time setting up telescope mounts.

Integrated Handle

The same goes for the built-in heavy-duty handle on the mount head. For those of you that lug a complete rig across the patio as I do, you’ll wonder how you ever got by without this. I can get one hand between the mount head rod and spreader, and the other with a tight grip on the handle.

With the Esprit 100ED APO and astrography accessories attached, it’s a heavy load. But at least I can carry it more confidently with the integrated handle.

Built-In Polar Finder Scope

With polar alignment being so critical for success, it’s a shame when a telescope mount either doesn’t include a polar scope, or it feels like an afterthought. I’ve always enjoyed the practicality of a built-in polar scope, and making adjustments to the HEQ5 was a breeze.

I am happy to report that the polar alignment scope on the EQ6-R is easier to use than ever. The polar finder reticle is illuminated red when the mount is one, providing the perfect amount of light to see the clock and the Polaris at the same time. The biggest improvement to this process is the previously mentioned alt-az bolt upgrades which allow you to make smooth, precise adjustments.

SynScan Hand Controller and Slewing

The new and improved SynScan system is a pleasure to use, and I still enjoy the manual process of the 3-star alignment. Once your polar alignment has been set correctly, it’s simply a matter of slewing to 3 bright stars in your window of sky to quickly train the mount to point accurately.

I won’t get into exact arc-minutes of precision, but let’s just say my second alignment star appears in my imaging telescope (at 500mm) every time. After star 3, I can be confident that I’ll be pointing directly at my faint deep sky target with minimal framing adjustment before shooting.

The mount is quiet, even when slewing at top speed. It’s a high pitched hum that reminds me of the HEQ5 motor, but refined. It’s certainly not loud enough to wake up the neighbors. The new and improved SynScan hand controller (Version 5) is connected via USB. This makes updating the hand controller firmware much easier using your PC.

Tracking Accuracy and Autoguiding Performance

For those of you that like to scrutinize the tracking accuracy of your telescope mount using the graph in PHD2, have a look at the screenshot below. For my image scale using the Esprit 100ED and ASI294 MC Pro, the total RMS error of less than 1.0 means that my 4-minute images came out very sharp. I don’t like to get too hung up on the numbers in PHD2 guiding (and you shouldn’t either!), but if you’re curious as to what I’ve observed with the EQ6-R – here it is:

The Images

When I have enough information and experience with the Sky-Watcher EQ6-R, I’ll provide a detailed review of the mount that includes the specific traits of the hardware including any backlash, and any quirks that come up with different telescopes riding up top. For now, I’ll share 2 the two images that were captured on nights 1 and 2 using the EQ6-R with an Esprit 100ED telescope.

For both images, the ST-4 autoguiding port on the EQ6-R was used to improve the tracking of my deep sky targets. At this time, I have not attempted any unguided images with the EQ6-R, although that would be an interesting experiment.  To autoguide, I leverage the free PHD2 guiding software with my compact guide scope package that includes an Altair GPCAM2 camera and StarField 50mm guide scope.

  • Filter: STC Astro Duo Narrowband

As you can imagine, I am quite impressed with the performance and user-experience the Sky-Watcher EQR-6 telescope mount has provided thus far. For the style of deep sky astrophotography I enjoy, it appears to be a great solution and upgrade from the HEQ5.

The wide-field Sky-Watcher Esprit 100ED is a perfect match for this mount, and I’m not just talking about the color scheme. For an idea of the different types of telescopes, you could potentially mount to the EQ6-R,  have a look at the AstroBackyard Facebook page. The announcement of this GoTo mount stirred up many backyard images of the EQ6-R in a variety of configurations.

Final Thoughts

I am very grateful to be in a position to be reviewing and enjoying astrophotography equipment in my backyard. Some tests span the course of multiple nights and even months. The steeper the learning curve, and the more hiccups that occur along the way – the longer it takes to share organized content and results.

With that in mind, the Sky-Watcher EQ6-R Pro arrived at my home 1 week ago today. Regardless of my previous experience using my old HEQ5 and equatorial mounts in general, this is a pretty impressive testament to the painless user experience this intermediate level equatorial mount offers.

The Sky-Watcher EQ6-R offers a good balance of affordability and performance/payload capacity. It’s an attractive option for anyone using a modest-sized refractor such as the Esprit 100ED and leaves room to grow into the future.

To stay up to date with AstroBackyard and my latest backyard adventures with the Sky-Watcher EQ6-R and everything else I’m up to, please subscribe to my e-mail newsletter. I’d like to thank Kevin at Sky-Watcher USA for this incredible opportunity. I think he finally got tired of seeing me drag that old HEQ5 out of the garage!
