M22 Globular Cluster - Unguided!

After several hours fiddling in the dark and cursing while all the cool stuff slowly dipped out of my yard's viewing area and into the trees, I managed to image this globular cluster.

The only reason I wasn't guiding is because PHD kept seizing every time I used Backyard EOS. I'm guessing the USB2 ports can't handle the new SSAGpro mono guide cam and my DSLR (both USB3) at the same time. Hopefully a powered USB3 hub will fix that?

I also didn't know what I was imaging until later when I ran the result through http://astrometry.net/ (What an amazing website) and it told me, in great detail.

Features : M22 and HD171961
Taken Sep 17th from Byron Bay NSW
10 x 30s exposures / unguided (+ same # exposures + time for Dark frames)
Celestron c9.25” SCT and CG-5 Mount
+ Focal Reducer (F 6.3)
Canon 70D + Backyard EOS
Stacked using Nebulosity
Original File Resolution : 5546 x 3682

I'm a little bit shocked it turned out at all! It's a small success for me in the pursuit of deep space astrophotography.
