M31 with a 10D and Epsilon160

Well, due to mount troubles, I've been quiet a while, but I was finally able to exercise my cameras this past weekend. Last night, I captured a little over an hour of M31 using my Tak Epsilon 160, which is a fast f3.3 Newtonian...perfectly matched for the 10D. I used ImagesPlus's newest and greatest features and must say it worked superbly...the adaptive dark frame subtraction made for a much more noise free final product. I did little noise suppression, really.

Anyway, the final version and more details are here:

Comments/suggestions welcome.

Excellent image. The low noise level is amazing.

Rick,

Thank you very much. This is the best M31 I had ever seen from Epsilon 160!

Do you mind telling us more about the adaptive dark subtraction?

Fantastic image Rick!

I have used my old Canon AT-1 on my telescope, but I do find focussing (particularly on dim objects) somewhat problematic. How do you accomplish such good focus? Do you have a different focussing screen, or can you view the image on your computer through a link of some sort, similar to a regular CCD? I would think the latter would be the case, but I would like to know.

I need a new SLR to replace the AT-1 and if I can find one that would double for astrophotography, well... that woud be great. Clearly the 10D is a prime candidate.

Sorry for sounding inexperienced, but... I am.

Derrick.

Rick,
That is an awesome photo. Congratulations.
