Why I Built a Backyard Observatory
In this article, I’ll explain why I built a backyard observatory, and how the entire project took shape this spring. Officially named “Black Dog Observatory” this structure will become the epicenter of my astrophotography operations in the backyard.
Below, is a photo of me standing in my new SkySked POD XL5 observatory. I expect many memorable nights in the observatory this summer.
My backyard observatory
After 10 years of setting up my camera and telescope for astrophotography each night, I finally have a permanent setup to photograph the night sky.
Because the base of the telescope mount is bolted to the ground, lengthy polar alignment routines are a thing of the past. This is one of many time-saving realities of owning a personal observatory.
In general, my deep-sky astrophotography sessions will start sooner, last longer, and happen more frequently. This is largely due to the fact the entire kit will stay outside under the dome at all times.

I named the observatory after my loyal companion, Rudy. It also pays homage to my Rock and roll roots (Led Zeppelin song) as my father and I were both drummers, and the owner of SkyShed (Wayne Parker) is a bassist.
This 8-foot wide by 8-foot tall dome will house my equatorial telescope mount, primary imaging telescope, astronomy camera, and all of the other accessories needed to run a deep-sky astrophotography session.
This project has been in the works for nearly 6-months, and to finally see the observatory sitting in the backyard is a dream come true.
Timeline of Events:
- December 12, 2020 – Discussions with Wayne Parker about an observatory
- January 26, 2021 – Lengthy conversations convincing my wife to get on board
- March 17, 2021 – Ordered materials for wooden deck, and concrete footing
- April 29, 2021 – Picked up steel pier from factory
- April 30, 2021 – Selected location of the deck and dug a 4-foot hole
- May 1, 2021 – Constructed 12′ x 12′ floating wooden deck, poured concrete
- June 9, 2021 – Rented truck and 12′ trailer, picked up SkyShed POD
- June 16, 2021 – Completed construction of observatory and mounted steel pier
I chose a location in my yard that had the best view of the southern horizon. This is where many of the best deep-sky objects in the night sky reside. It also has a clear view of the North Star, Polaris, and decent views to the east as well.
The height of the observatory platform helps me see slightly lower on the horizon, which is handy when photographing and observing objects near the core of the Milky Way.
I selected a location with good views to the south.
The observatory walls, bays, and dome are fastened to a 12′ x 12′ wooden deck that sits 1-foot off the ground. In the center of the deck is a hole that allows a steel pier to anchor the telescope mount to a 4′-deep concrete footing.
I also built a conduit underneath my lawn to run household AC power to the observatory. I ran a 75′ heavy-duty outdoor (contractor grade) extension cord through the 2″ ABS pipe, and the outlet arrives at the base of the pier in the center of the floor.

The steel pier is bolted to a concrete footing underneath the deck floor.
As you can see in the photo above, the steel pier rises up from beneath the wood floor, so that it will not be disturbed when I walk around on the deck floor.
Wayne informed me that the height of the pier was an important measurement to consider. I settled on a height of 32″ from the floor to the top of the pier mounting plate.
This height is low enough so that my long refractor telescopes have plenty of clearance of the dome closure, but not so low that my view of objects low in the sky are obstructed.
The SkyShed POD XL5
SkyShed Observatories is a Canadian company based out of southern Ontario just like me. Last year, I talked to the owner Wayne Parker (bassist for Glass Tiger) about my current situation of hauling gear in and out of the garage night after night.
A backyard observatory is something I’d always dreamt about, but committing to a permanent setup was something I struggled with for a long time. It wasn’t until I saw a clear game plan laid out in front of me that I was ready to take the plunge.
Wayne began sending me an extensive list of resources to fully understand the construction process. He also provided me with a list of materials and instructions to build a concrete footing for the pier.
The observatory in my backyard is a SkyShed POD XL5. This model includes 5 POD bays for things like a computer desk, beer fridge, and even storage of astronomy equipment.
You can order the POD with as many bays as you want, from 0-5. There are also some cool upgrades to consider, like the PZT hardware kit. This allows you to slide the dome roof over in a roll-off observatory style manner.
The observatory itself is made of high-quality polyethylene plastic, and you can order the structure in a variety of colors. I chose light gray walls with a white dome as I felt this was the most modern color scheme, and that it would look best in my backyard.
These POD’s can be found all over the world. I guess you could say that I’m a part of the POD family now!
Why Build a Backyard Observatory?
A backyard observatory allows you to collect new astrophotography images on a more consistent basis. Because the telescope is always set up and ready to go, your camera can begin collecting photons sooner.
Because the polar alignment, balance, and even plate-solving and pointing models are already in place, a permanent setup will save time and maximize the amount of data you can collect in a single night.
On most clear nights, I will still run multiple astrophotography rigs in the backyard, but the observatory data will be my bread and butter.
One of the reasons I hesitated on building an observatory was the thought of being un-relatable to the average amateur astronomer.
Rest assured, I will continue to test and share information about techniques with beginner and intermediate-level gear in the backyard.
A look inside of my observatory.
Inside of the observatory is a Paramount MyT. This is telescope mount is on loan from the supportive folks over at Software Bisque.
The Paramount MyT is an observatory-grade telescope mount, that will allow me to tap into some serious automation features, but there is a huge learning curve as well. I’m not going to lie, this thing scares me.
I have no idea how long this loan will last, but I’ll need to get up to speed on the functionality of this telescope mount ASAP. I will be using TheSkyX Professional Edition to run the mount, which is entirely new software to me.

In terms of telescopes, I’ll mount the William Optics FLT 132 APO on this mount for now, but it’s an evolving setup, and I’m not entirely sure what the final kit will look like.
I want to start using an electronic focuser on a more consistent basis, and the observatory rig is the perfect opportunity to finally nail down a reliable system.
Over time, the idea is to get the observatory as automated as possible. My goal is to get everything ready before winter, because our winters in Ontario, Canada can be harsh.
So far, I’ve spent one night inside the observatory, and it was a surreal feeling. Wayne told me I would experience the “dome-effect” and I can honestly tell you I got chills.

Wayne Parker has been incredibly helpful and responsive through this entire process. I am astonished at his commitment to his customers and willingness to help.
He generously donated the observatory structure to me for this project and was instrumental in its completion. He did not ask for anything in return, nor does he have any say/review over the information I share about it.
I am quickly realizing that SkyShed POD owners are a loyal and active group. I’m confident that this observatory will last a long time and potentially move with us to our next property.
For now, I’m going to try and focus on enjoying the conveniences of a permanent setup, although there is still a lot of work to do. I am looking forward to the process of automating many of the routines I have grown used to for astrophotography.
I still can’t believe I have an observatory in my backyard!
