I have a ZWO 120MC-S in use as an allskycam. I am using AllSkEye software.
I seem plagued with a noisy sensor. After dropping my exposures down to 5 second, I seem to have no clearer images! I started with 45 seconds and could view the MW. I dropped gain down to 20.
I've used both Darks and Bad Pixel Mapping - though there appears to be little to chose in terms of image clarity.
Am I on a lost cause with this camera? I have a peltier, but the chance of me being able to attach it to the camera is fairly small!
My Dark attached for comments. (15 * 15 second exposures)......and an image ( @ 15 seconds )....
