Not as good as I'd hoped - need longer or a load more subs but as I'm on a roll........................

Mick,

Which night did you take this? 

This isn't as good as your Pleiades but the Andromeda Galaxy is a surprisingly difficult target to get right.

Anyway, well done - it's great to see you imaging!

Thanks Mark

Well done another good start :-)

Mac

excellent.

even got the other two as well m110 & m32

thats very good for unguided as well.

there's now stopping you now

Had a go at reprocessing this - Darks didn't kill amp glow - subs too long for unguided at 3 min.

That's looking really good Mick, you're going to have to get the guiding thing started!

Mick - that's a great reprocess. 
Much better than the first.
The processing will make or break an image and I think you've definitely made the most of your data here.

Don't worry about the prominent amp-glow - the darks don't quite match the lights but it's not a big problem - there are other tricks I know of to use to isolate it and subtract it.

That's a good reprocess, yes there are few problems but you can't expect to get everything spot on first time.  It's an iterative process.  Mastering your equipment, calibration and image processing all take time.  The good thing is you've made a great start.  I'm certainly looking forward to your first guided image!

Much better Mick. The focus is off on the original image so it will never be fantastic, but despite that it's darned good.

Nice processing Mick,
