Date of image 02/11/2016
M 108 Galaxy near the Owl Nebula.
Hardware details: Camera: Canon 600D (astro modded). Telescope: SW Evostar 120 with Baader UHC-S filter. Mount: AZ-EQ6 guided using a ST80 synguider. Image details: Lights: ~30 x 3min at ISO 800, Darks: 50 x 3min at ISO 800 (from dark library), Lights and darks separated by 15 sec intervals. Flats: 50 x 1/350s (taken from laptop monitor screen) at ISO 800, Bias: 50 x 1/4000 at ISO 800.
The weather was excellent - no clouds during the whole night. I was able to image until tiredness got the better of me.
Processing was done in DSS, I increased the saturation by 30% and manually aligned the colours. This target is a kind of default goto object since it rises after many other objects of interest for me. I tried to image this and the Owl nebula in a single frame, which put M 108 at in the corner of the frame. As a result there is a small amount of aberration (probably caused by some tilt in the sensor). It might be better for me to centre the galaxy in the frame and lose the Owl nebula.
