Northern Cygnus Wide Field Test

3 * 5 minute exposures of the Northern Cygnus region. Another wide field test with my Sigma 10-20mm HSM mounted on my Celestron CGEM. The upper right bled into some light pollution, so I created a background gaussian blur, subtracted it as a layer and this is the result. Very rough image, no flats, darks or bias frames taken which is a SIN with a DSLR in warm temperatures! A sin I say! Fun learning curve, though. Wide-field astro is very different to DSO astro imaging!

Cygnus Wide Field

The Cygnus constellation is a pretty one to look at given the right time of year and the right conditions. The Milky Way winds itself right down through the constellation, and as a result it's quite a "busy" place to observe. At this time of year it is right overhead. I have seen some folks take lovely wide field shots of this area of the sky, so thought I would give it a try.

I managed to capture some Milky Way structure. There's some noise from the camera at upper right. I am finding that a bit annoying, maybe I need to take dark shots even for my wide field attempts. (?)
