Another image from uncooled cam86, 78x 1s exposures through SW 10" dob. I did 100 images but lots were blurred as I had to nudge the dob several times during the acquisition to keep the target in sight.

Ignore the trailing, 1s is clearly too long exposure without any tracking.
0 gain and 0 offset, no binning.
Ambient temperature was about 20 degrees C.
3D-printed camera housing with several light-leaking holes at the back for cables.
The cam worked perfectly with APT (Pat thanks for the tip).

I noticed that 3 images out of the lot had higher noise than the rest. They were consecutive images in the middle of the sequence. Not sure what happened there.

Also, Pat and Filip, I vaguely remember reading somewhere that we should use several (4?) seconds pause between exposures. Is this right or is my memory playing tricks on me? I used 1s between exposures for this photo and everything seemed OK.
