Meade 70mm Quadruplet APO

Meade 70mm Quadruplet APO Review

|Telescopes|18 Comments

The Meade 70mm Quadruplet APO is high-quality imaging refractor for wide field astrophotography. This compact telescope utilizes FPL-53 ED glass to produce images with impressive color correction. The quadruplet lens system design results in an ultra flat-field, without the need for an additional field flattener.

In November, I was given a chance to test the Meade 70mm Astrograph in my backyard. My excitement for this telescope should come as no surprise, considering my love for apochromatic refractors. The biggest question on my mind was just how flat the field be when using my DSLR camera. In this review, I’ll share everything I know about this stocky white refractor.

Key benefits of the Meade 70mm astrograph are extreme portability and lack of field flattener needed for astrophotography

You may remember seeing some images shared on social media using the hashtag #astrobackyardchallenge.  These photos of the Soul Nebula were captured using a Canon EOS Rebel T3i DSLR through the Meade 70mm Quadruplet telescope. The RAW image data was processed by several talented amateur astrophotographers from around the world.

For a hands-on astrophotography image processing tutorial, be sure to check out my YouTube video using Photoshop to produce the image below. This image was captured from a red-zone using 5 hours of total integrated exposure time.

Meade 70mm Quadruplet APO Review

The Meade 70mm Quad is heavier than you might think.  It outweighs the William Optics Z61 by a more than a pound, which is substantial considering it is only 10mm wider in aperture.  The extra weight is, of course, due to the quadruplet-element design (more glass!).  I’ll take a little extra weight if it means near zero detectable color fringing every time.

At first glance, the price tag may have you wondering whether the Meade 70mm Quadruplet APO is worth the extra cost.  For a true comparison of price against the competitors, be sure to factor in the accessories included with the Meade including an aluminum carry case and DSLR camera adapter.

Factor in the price of a dedicated field-flattener/reducer when comparing the prices of competing telescopes in this range.

I have filmed a video review of this telescope on my YouTube channel. This may provide with a better look at the features of this refractor hands-on. Please be sure to subscribe to my channel for more astrophotography telescope reviews, tips, and advice.

Adding a Guide Scope for Astrophotography

The built-in finder scope bracket offers a convenient solution for mounting a small guide scope right away. When setting up, I use a small finder scope to star-align my mount. I then swap the finder scope out for a guide scope using the same universal bracket.

I have mounted an Altair 60mm Starwave Guide scope, with an Altair GPCAM2 AR0130 Mono Guide Camera. For me, the balance of this configuration was a bit off, with the back end being a little heavy. This issue could be rectified by mounting the Meade to a longer dovetail plate to properly balance the declination axis of the load.

Even with the slightly unbalanced load, the Meade was not an issue for my Sky-Watcher HEQ5 mount during the imaging session. The telescope is so small and compact, that the counterweight sits right at the top of the counterweight shaft.  The Meade 70mm Quadruplet Apo is likely within the limits of a small tracking mount such as the iOptron SkyGuider Pro, but I have not tested this.

Connecting a DSLR camera for astrophotography

I must say, this was a straight-forward process, as the camera threads directly into the focus tube. The connection between the optical tube and the included 48mm-42mm camera adapter is locked-in for the long haul. Simply unscrew the color matched blue cap at the end of the focuser, and screw the DSLR with the adapter into place.

Since I shoot with a crop-sensor DSLR, the 48mm-42mm adapter ring was needed to connect my camera to the scope. This adapter is included with the Meade Astrograph package and has its own spot in the padded carry case.  The adapter fastens securely to my Canon EOS T-Ring. A full frame camera would thread the 48mm t-ring directly into the telescope without an adapter.

The collar of the telescope is rotatable with a locking screw, so you can easily adjust the framing of your target from portrait to landscape. The collar is rock solid, even after changing the orientation of my target in the image frame, I did not need to adjust focus whatsoever. Razor sharp focus is one of the many benefits of an apochromatic refractor, especially at this focal length.

Early Results and Impressions

At f/5, this refractor can collect a lot of light in a short period of time. This focal ratio is faster than all of my previous Apo’s including my beloved Explore Scientific ED80 (f/6). The added photon collecting power was felt when capturing images using short 2-minute exposures from the backyard. Even at ISO 800, I was quite pleased with the amount of nebulosity showing on the Soul Nebula project.

My individual light frames through the Meade Apo showed impressive contrast from the city. As expected, the field was completely flat to the edges of my APS-C sensor DSLR, and the stars were tiny and razor sharp.  You wouldn’t know that we had wind gusts of up to 70kmh the night this single frame on the California Nebula was captured.

The image below was shot at ISO 800, with a SkyTech CLS-CDD Light Pollution Filter in the camera body.

The stocky Meade 70mm Astrograph is solid and secure. With no field flattener to extend the imaging train and a modest overall tube length, the wind will likely never be an issue when shooting astrophotography with this scope.

The focal length of this telescope is 350mm.  Not surprisingly, this telescope specializes in wide-field imaging of larger deep sky objects such as the North America Nebula, Andromeda Galaxy and the California Nebula as seen below. When you’re shooting this wide, guiding accuracy is much more forgiving. This is one of many reasons I recommend a small apo refractor to astrophotography beginners.

My final processed image of the California Nebula utilized 3 Hours and 14 Minutes worth of total exposure time. 97 individual light frames of 2 minutes each were stacked in DeepSkyStacker and processed in Adobe Photoshop. NGC 1499 is a large emission nebula and showcases the wide field of view produced by the Meade Apo.

Limitations and Expectations

For astrophotography purposes, it’s hard to find negatives about the Meade 70mm Astrograph, other than price. At $1,199.00 USD MSRP, it certainly worth a conversation with your better half before making the plunge.

The drawbacks of this telescope are typical of all refractors of this size. The Meade 70mm Quadruplet will not excel at visual planetary observing, there is simply not enough aperture to pull in the fine details of the cloud bands in Jupiter, or spot the Encke gap in Saturn.

Also, If you are looking for deep, up-close views of smaller galaxies, you’ll want something with much more focal length. Like I said, this telescope was built for wide field imaging!

The Verdict

The Meade Series 6000 ED APO Refractors are well known in the astrophotography community as top contenders for deep sky imaging, and this quadruplet is no different. Take a look at the stars on the edges of my image frame when using a crop-sensor DSLR like the Canon T3i.

Full-frame camera owners will be happy to hear that the Meade 70mm quadruplet apo has a fully illuminated image circle (42mm) that will cover the entire camera sensor. The included adapter comes is a welcome addition to APS-C sized sensor DSLR astrophotographers like myself.

Features like a retractable dew shield and precision focuser are expected on a telescope in this price range, but also well appreciated. The padded aluminum carry case will get a lot of use thanks to the portability of this refractor, and the potential for serious deep-sky astrophotography while traveling.

I have enjoyed my time with the Meade Quadruplet over the past month. The telescope sets up quickly, and I was up and running on my target within 20 minutes of  Polar Alignment.  For anyone looking to capture exceptional wide field images using a DSLR, it’s hard to beat the convenience of a small refractor.

Smaller equatorial telescope mounts such as the Celestron Advanced VX or iOptron SmartEQ Pro will have no problem tracking the night sky with the Meade Quadruplet on top.

The Meade 70mm f/5 Quadruplet ED is proof that you do not need a large, heavy telescope to produce incredible astrophotos.
