Thanks guys for the feedback.
I guess I was all fired up last night having finally got the auto-guider, etc. working and was expecting a bit more from my shot....ie perfection. I'll take all the feedback on board and will take some 5 & 10 minute subs when there's no moon about. What size light pollution filter goes in front of a DSLR? It won't be a 1.25" as I'm connecting the DSLR directly to Newt.
In the meantime I'm going to try a few processing techniques that I've found in my journeys along the information super-highway. If anything good comes out of it I'll let you know!!!
Update: Here's an image I'm happier with....
Cheers,
Mario
