So after my tracking nightmare I managed this tonight. 30 lights at 61 secs, 30 dark, ISO 800. Tiny piece of editing in GIMP because I don't really understand it!! I'm pleased with it.

I am pretty poor at processing, but I had a go at stretching your jpeg data as I thought there might be scope for more data to be pulled out, and I think there is. However, vignetting stops it being stretched much more, here is a capture of the vignetting I've pulled out to over emphasise the problem. I suspect if you did some flat frames this would help reduce the vignetting and allow you (or someone else) to stretch future data a bit more. As I say, I don't thoroughly understanding imaging or processing, but that is my understanding anyway. I'll find a link to explain vignetting in a minute. Your VERY much stretched data below:

Found a few links which might offer you some help. However, I don;t want to detract from the fact this is a cracking image, and one I'd be most proud of having taken.

Thanks guys, my Canon isn't modded. I haven't done any flat frames as yet but I guess that's a logical next step.
