Backyard of the Week | September 27, 2021
The AstroBackyard Backyard of the Week highlights astrophotography setups from around the world. A “backyard” can be a balcony, driveway, garden, or wherever else you set up astrophotography equipment at home.
By taking a behind-the-scenes look at the equipment amateur astrophotographers use to take deep-sky images, you can get a better understanding of the process.
This week’s backyard astrophotography equipment profile comes to us from Marcus Saldanha in Canada.
Location: Vancouver, Canada
Marcus uses an astro-modified Canon DSLR to photograph galaxies, nebulae, and more through his 8″ Meade SCT. His telescope provides 2000mm of focal length to work with, but he speeds this system up 0.63X Celestron reducer lens.
The assorted pieces of gear that make up Marcus’ complete imaging system lead me to believe he purchased many of the items second-hand. This is precisely how I managed to put together an affordable deep-sky imaging rig my first time around as well.

I have a soft spot for those setting up their gear on a balcony. On one hand, you have the advantage of elevation and a low view of the horizon, on the other, a large portion of the sky is completely obstructed.
However, astrophotography can still be enjoyed in a scenario like this, you just have to get a little creative with your setup and alignment routine. Marcus has clearly mastered this process and has completed an impressive number of astrophotography projects from his home.

What does Marcus love most about his gear?
“Very versatile as it lets me search the night sky at a measly ~1300mm (F/6.3); Perfect for small galaxies and getting that fine detail in nebulae. Also, I can easily set it and forget it as Astro Photography Tool runs my imaging plan while I enjoy the warmth of my bed.”
The Canon EOS 60D is a capable camera for astrophotography, with several traits that come in very handy for photographing the night sky. Marcus’ 60D, is astro-modded, essentially turning it into a Canon 60Da.
The camera includes a flip-out display screen, which makes tasks like focusing and framing your target easier. The 5X-10X live view video mode is a life-saver, and noise levels in the ISO 800 – 1600 range are respectable.
Thanks to an after-market full-spectrum modification, this camera can record detailed images of nebulae emitting light in the H-Alpha bandpass.

Marcus uses a mix of broadband and narrowband filters to photograph deep-sky objects. For broadband, full-color images a Lumicon UHC or Svbony UHC clip-in filter is used.
When the moon is out, or serious narrowband h-alpha details are needed, Marcus uses an Astronomik 12nm Ha filter. A combination of light pollution filters and narrow bandpass filters (specially Hydrogen-Alpha) can help create dynamic images of nebulae and galaxies from the city.

Dumbell Nebula by Marcus Saldanha
Marcus uses a Meade 8″ SCT to capture distant objects in space from his backyard. Thanks to its large aperture and long focal length, this telescope is capable of pulling smaller galaxies in for a closer look.
The native 2000mm focal length is great for small galaxies and photographing planets. For a wider field of view and faster light gathering ability, a Celestron 0.63X reducer is used.

- Focal Length: 2000mm
- Focal Ratio: f/10
- Weight: 17 lbs (7.7 kg)

The Telescope Mount
Marcus uses a Sky-Watcher HEQ5 Pro computerized GoTo telescope mount to run his imaging sessions. The telescope mount is connected to his computer, so he can leverage tools such as plate-solving via Astro Photography Tool.
The HEQ5 Pro has a maximum payload capacity of 30 pounds, which is enough for Marcus’ 8″ SCT, camera, and a small autoguiding system. This telescope mount has been around for years, and HEQ5 owners continue to enjoy reliable tracking and impressive performance for the price.
The Guide Scope
The Antares VS60 “VersaScope” is a finder scope/guide scope with a diameter of 60mm. It has a focal length of 227mm at F/3.78, making it a suitable guide scope for most refractor telescopes as well as longer focal lengths OTA’s such as Marcus’ 8″ SCT.
I haven’t seen too many of these bay boys, but they still come up from time to time on the astronomy classified sites.

The Guide Camera
It’s a simple 1.2 MP monochrome CMOS camera with a built-in ST4 autoguiding port and a USB 2.0 connection. The camera is ASCOM compatible, meaning it will work with PHD2 Guiding and APT to make guide corrections and dither between exposures.
