M31 for the n'th time

[oernulfs]

3 hrs 15 minutes, approximately. I am more satisfied with the colors now.

Shot through my WO 90mm with an Atik 383L+ color cam on a cgem mount. Darks, no flats.

Thanks for looking.

Quite nice Earnulf, I forget how big m31 is, would love to image it one day, any reason you didn't apply flats?

Cheers,

Russ

Yes, I have tried flats once, and ended up with a horrible result.

I really need some hints on how to capture flats (how to evaluate the correct exposure time) and how to stack them (I use DeepSkyStacker).

Any hints?
