Second DSO (first session): Andromeda

Peter Reader

Recommended Posts

Hi all!

As explained in earlier post tonight was my first DSO imaging session.

Here's my attempt at Andromeda and companion galaxy by the looks of things:

115 x 12s

ISO: 800


What effect will changing the ISO have on the fainter areas of the galaxie? Will these be clearer?

Will increasing exposure do this?

Thanks for all the support

Congrats on bagging M31 in your first session!

Yeah, more exposure time. Push up the length of each exposure - your tracking looks great at 12s so see how far you can push it! That many subs at say 1m or 2m would reveal a lot of extra detail.

Edit: ISO800 should be a good choice. Stick at this and up your sub time as much as your mount will allow.
