M31

I think this one and the Triffid Nebula are my favourite shots from 5 years of astrophotography M31 is quite a tricky one to get right and it took a lot of effort to finally capture the data I needed to draw out all the detail. Not just that but the learning curve required to get the processing methods was a good 3 years work so don't be disappointed if you try and it just comes out all wrong keep on going and you will get it right remember, no pain no gain in this game.
