Here's my latest attempt at M31:

Image

16 out of 23 frames stacked in DSS. Each frame 120s long, ISO800 @ 400mm f5.6

Combined and stretched in DSS and finished in CS4.

Lots wrong with this which I can learn from, the main issue being that it looks like light is entering through the viewfinder so I will close this off next time I am out.

Thoughts and comments appreciated.

It really looks like mine :lol:
Try the drizzle mode of DSS, it will zoom further without any lose of quality, plus you will get more detail.

P.S. I like it :twisted:

BTW, do you have an (auto-)guider?
120s with 400mm is impossible with my mount. (howeverm, to set the mount to Polaris is very difficult for me, 30s with 200mm is the longest I could get)

Hi Ruben,

I currently don't guide but plan to soon. I've recently been able to get 3min subs with my scope (1200mm effective focal length). It all comes down to getting the scope level, accurately facing north and accurately aligned with Polaris. With my mount the latter is easily achieved (with practice) due to the inbuilt polar scope.

I woul post my latest attempt with my 3min subs but there are other factors that ruin the end shot - still practice makes perfect.

What mount do you have? 3 min without guiding is really difficult!

Ive got a cheap EQ3-2 with motors and I find that Ive not discovered 1% of its possibilities.
I dont have the money to have such a mount, so Im quite happy with it.
