Old data re-processed with PixInsight. I can't find an earlier version though... I suspect that was around the time I found Deep Sky Stacker but got frustrated by the output stage of it.

4 March 2011. 23 subs of 30s. 450D, Canon EF 300mm f/2.8 at f/2.8 ISO400. I've never got the running man so clear myself, but he's still hiding in the noise so I can't bring him out further than this. Can't wait to have another go at imaging this one!

Stunning! I really could do with a clear night to have a go.

Another Pixinsight play on old data. This is a total of 20 minutes exposure with subs from 30s up to 4 minutes with apertures from f/2 to f/2.8. It was a right mix, and I just threw the lot in the pot to see what happens.

Again it is with the unmodified 450D, CLS filter and I used some 50mm lens but not sure which one now.

This would obviously benefit greatly from the now modified sensor. Still you can make out the faint Barnard's Loop around the lower part of Orion, as well as the more well known suspects in the middle. I really want to have another go at imaging this!

Thought I'd throw more data at the stack and see if it helps. I thought there was more detail but comparing it to my last attempt above I don't think it looks much different...

60 shots mostly 30s and few 120s thrown in too. Same kit as above. I got some 240s ones too but I didn't use those as trailing was getting obvious. But maybe I should just to see what happens?...

I did it after all. Threw in almost everything. 74 shots, same as above but with more 2 and 4 minute exposures. The 4 minute ones had significant trailing which I'm quite impressed PixInsight dealt with fairly well by using a non-trailing image as reference. You may note some black dots introduced on bright bits though, particularly with this tighter crop. The 4 minute exposures helped with the overall brightness a bit. Also I played around with curves in PI which I think helped balance the noise and low level detail better than I can with PS.
