Setting up my Astrophotography gear in the dark
Setting up my astrophotography gear at the CCCA Observatory using only red lights to preserve my night vision.
I had a long, eventful night at the CCCA Observatory this past Saturday. I wasn’t even planning on going, as a heart-breaking defeat of my Toronto Raptors at the hands of the Brooklyn Nets was fresh on my mind. I started packing up my astro-gear at 7:45pm. With the sun setting at 8:05pm, and a 45 minute drive ahead of me, I knew I would be breaking one of my own astronomy rules: Setting up in the dark.

By the time I arrived, it was pitch black, with only the stars and my red headlamp to light my way. I witnessed some amazing views of Mars and Saturn through my ED80 before setting my DSLR up for a night of astrophotography. I forgot a key element of any astrophotography imaging session, my guide scope. Forgetting something at home that is essential for imaging is always a frustrating experience. I knew my plans of taking 5 minute exposures of the Seagull Nebula were ruined.

I decided to take some 30 second unguided exposures of the globular star cluster known as M3. I have seen this cluster through a 20″ dobsonian telescope, and to this day, it is still my favourite sight through a large telescope.

Next, I chose to image a galaxy in the constellation Canes Venatici known as M63, or, the Sunflower Galaxy. In hindsight, it was not such a great choice, considering it’s size and my limited exposure time.

The good news is that this was really a “bonus night” anyway, as the moon rose early at about 1:00am. By then, some friends had come to join me and were dazzled by views of Saturn.  The next 2 weekends are when I really plan to get some good imaging done!

Okay, I realize that the image above isn’t very impressive. My darn unmodded Canon Xsi isn’t picking up the reds the way an astro-modded one would. I think another 2 hours would really help.  It’s always a delicate balance between pulling out data and keeping noise under control when processing an astro-image.

Thanks to a friend at my Astronomy Club, (RASC Niagara Centre) I have been given a few invaluable tips to progress my astrophotography knowledge further.  Namely by using the Backyard EOS software for acquiring images in the field.

Currently, I use Canon EOS Utilities to run my camera and has been working fine, but Backyard EOS has features catered towards astrophotographers.  The main feature I am interested in is dithering.

Another thing I am excited to try is stacking my raw files in photoshop rather than deep sky stacker. I have recently upgraded to Adobe Photoshop CC, and so far I am loving it. The updates to  Adobe Camera Raw (ACR 8.2) and improvements to the sharpening tools are outstanding.
