M31 Sept 5th 10" Dob

[Space Cowboy]

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 :

Very nice image, especially using a Dob. Thanks for posting.

Nice detail, especially for 15sec subs. Well Dionne

Thanks! Should mention I used a unmodified 1000D.

Good stuff, 20 mins of 15sec exposures worked well through your dob. Seems like you nailed it.

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.

Good result!

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.

Sorry to dig this post up but would I be able to use this setup for the comet? I'm thinking FOV wise?

The FOV would be sufficient to catch it, you won't get the full extent of the tail though as it's quite long - I attempted an image of it the other night with a FOV maybe 1.5x the above and still the tail seemed to go off the edge of the frame.
