CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!

Hi,
Thanks. I stacked 9 2min and 1min exposures.
You need to stack a lot more...
Anyway I stacked the final upon itself and got some other detail appearing, but thats cheating right.
This won't work, because both image are the same and nothing is gain.
As you stack more, the signal-to-noise ratio will increase and the shape of M31 will become more distinct and will look better.
Have a nice day.
