M31 Sept 5th 10" Dob

Recommended Posts

Having another crack at M31 with the Dob. Collected 20 mins of exposure in 15 sec subs last night though the sky was very hazy.

Stacked in DSS with 5 darks. Curves and levels in CS2 and other tweaks in image analyser :

Cheers! 15 secs seems to be the limit for the Dobs tracking. I did try a couple of 20 sec sub's but the stars were looking ropey. A properly clear sky would produce decent results though the focal length does reduce the fov for a large target like Andromeda.

Thanks Chris! Will be interesting to try some smaller targets with my qhy5l cam if I can tune the GOTO as its not very accurate.
