Last night I tried to use my planetary camera for deep sky imaging, I picked the easiest target, the trapezium and surronding nebulosity. I figured I should make my first deep sky image as easy as possible :-)
No filters, and the slowest video mode I could set - one frame per second.
Prime focus, f/5.5 and focal length 1800mm.
This is a stack of 500 frames, with some dark drame subtraction etc, but there's clearly some artifacts still present. Not too bad considering the camera is not cooled.
Scope:

Capture details: 640x480 16bpp, 1 fps for 500 seconds.
dark frames subtracted.
cheers, Bird
