Great shot! You have managed to really highlight Barnards Loop.
15min exposures is pretty good. Is your Ha filter 7nm or 12nm?
The field curvature is due to the zoom lens. I don't think zooming in will help. Stopping down might, but then you will lose exposure.
The best solution is go on ebay and get a 2nd hand Pentax wide angle or standard fixed focal length lens. You will get better quality and greater exposure.
Is that the Crab Nebula in the bottom left?
Good luck, it's clear again tonight!
Take care.
Ross.
Thanks Ross. Baader Ha 7nm. Will have to try different settings.

In the very old old days (early 80's) of B&W film, to get this would have been a real triumph

Thanks Mike. I'm not up to the RGB thing yet. I'm pretty sure the stars would bloat without the Ha filter on.
Gee your website is really a credit to you now Marc. A treasure trove of great images.
Great Barnard too BTW!
Thank you very much Rob. Wish I could take the credit. I didn't do it. It's a windows live template. I do websites for a living and I don't even have one of my own... Few M8s in there hey? Practice makes perfect.
No spikes on this one eh?
