The light pollution removal tool I use (and have to) when I shoot from the 'burbs has a tendency to really knock off the noise in the background, hence the background looks clipped. I'll back it off when I do the second iteration of processing.

Again see above, the joys of shooting stuff like this from Melbourne!

So did I Trevor, but I pushed the data as much as I could without making stuff up. This is probably all I can do from home, I'd need to go to a dark site to get any more of the outer arms. The signal is probably there, it just can't fight through the LP.

Of course there's always the Mac v PC problem I have, as I process on a (calibrated) Apple 30" monitor and a MacPro, sometimes the gamma differences in the PC monitors and video cards make my pics look a bit dark. I don't know why this is, but they look OK on my work PC (also calibrated) and the 27" iMac (running Windows) that I'm using to post this.

Thanks Nettie, and all the other posters as well. If I can do this, anyone can. I'm thinkiing of posting a progressive M83, I reckon I've had at least three goes at it with varying gear. It'd be interesting to see the progression.

Cheers
Stuart
