Sadr Region in Cygnus

[Domain105]

After a bit of a break to build my garden observatory, I finally managed to get some imaging done.  It is my longest session to date - mostly because I did not have much setup or take down time and I let the imaging carry on late into the night.

Image details:

• 41 x 300s exposures
• ISO 800
• Canon EOS 450D (modded)
• No darks - only dither in PHD2 / Backyard EOS
• 10 x Flats using a light panel from Amazon used for tracing images etc
• 10 x Bias
• Bortle 8 skies in south Birmingham
• There was a full moon in Aquarius / Capricorn so not too close to Cygnus
• Skywatcher 150PDS, Skywatcher HEQ5 (Rowan Belt Mod), Skywatcher Coma corrector, Astronomik  EOS Clip filter for light pollution
• Processes in DeepSky stacker and Photoshop CS5.

I tried various amounts of stretches but the noise would get too much. I've not done anywhere near 3.5 hours of exposures before so am not sure if I should have caught more nebulosity or this is what 3.5 hours in my conditions should give me. Also I am really very colour blind (Red / Green) so my colours may be off to normal vision people.  Overall I am happy with it as I am still learning. Focus needs a touch improvement I think and also polar alignment was not too great with PHD2 having a disco keeping the RA in check. 

I hope you enjoy and if you do live in heavily light polluted skies, you can still do what I do and have a bash anyway!
