Try and shoot it at the highest possible elevation to avoid atmospheric scattering, collect more data and stretch the midtones a bit more.
Some people make the horse look easy, but it isn't!

Thanks Kevin for your opinion/advice. I definitely need to look at an astro CCD for these kind of targets. I can't do the camera right now but if the weather stays clear, the time i can do.

I knew i left something out Richard
I use ISO800 most of the time, including this one. I do this because I feel that there is a little less noise to deal with later on. In your experience (I've only been doing this for a couple of months ) do you think that the higher sensitivity of ISO1600 is worth the extra noise or am I going about it the wrong way?

It seems about right for a slow system and unmodded camera. Your camera is probably most of the problem here, if you were using a CCD and HA filter it would be much easyer.
I would also think a flattener would be of some use, as there is noticeable field curvature.

Peter, I don't know what i'm expecting, that's why I'm asking for opinions from people with more knowledge and experience than I
.
Just wanted to know whether I am on the right track, or if i could be getting noticably more from my setup, and improve my technique.
I noticed a little more detail in the horse head region with the extra stretch, but then the sky seems too light for my taste, so left it as it is.
You are right about the flattener though, i was hoping to use a focal reducer to speed the system up a bit, but there goes that i suppose
