Are you sharpening? The stars seem a bit crunchy.
The important thing is that you have the foundations of good polar alignment in the bag. Did you take flats?
You can use a few more iterations of curves to really bring out the detail in the dust lanes.
Top stuff -- you'll go far, Darrin.

thanks very much for your support in the past H!!. I have learnt a fair bit from you and I was very dissappointed I can't be there at AAIC as I really wanted to go (work committments unfortunately).
No sharpening done. No flats - I was too eager to try out the G11 and snap away. When I stretched, the image seemed to get "noisy" quickly. Perhaps not enough exposure time overall.

As for your image....wonderful result with very little exposure,nice work.

Louie, thanks very much. I have been closely watching your demonstrations on your site and I am limiting my self to stretching and curves at the moment but as I said to Humayun, the data quickly "blotches" or looks noisy after only 1 interation (and I checked it is indeed RAW). I can only assume there is only so much to do with 40 odd minutes of data at this ISO. But the mount is really a big step up and I just now need the clouds to bugger off.
One question though - how do you know you are "over" stretching? Ie if the image is starting to look rough/ragged after a stretch, is this an indicator you've pretty much hit your budget limit with the exposure/data obtained?
Cheers,
Darrin...
