Yesterday evening, a large break in the eternal cloud pack allowed at last some more imaging! Perfect for the first light of the ASI183MM and also the new guiding/planetary camera the ASI290MM.
During the imaging session, I could picture the setup before and after the streetlights were switched off…. Imagine the difference!
Processed with AstroPixelProcessor no addional Photoshop done.
Apparently the Gain setting was way to high my mistake, it should have been more around 50 to 120. Unity gain is 120 for this camera
This results in a rather noisy background.
Additional flaws for this first image with this camera are:
– the camera distance to the reducer needs to be adapted to avoid the elnogated stars in the corners
– Alnitak clearly marks it spikes in this image!
