I got out for 40 mins tonight, got some avi's and spend 2 hours today processing and combining three of them, the 1st image is an initial stack from Registax, the second is a K3CCD stack or 3xAVI, exported as FITS, combined in Registax 2 and then Wavelett filter applied in AIP4WIN and colour balanced in Photochop CS.

Just trying a PNG file as well, the JPG seems to loose detail on my screen.

Very nice indeed - what focal length did you use? Was this first light for the new observatory...? I think the small light patch area at about 2'oclock position might be Olympus Mons....? Perhaps someone else can check..? I like the colours - looks more natural than mine which is a little too 'orangey'..

Hi,
I think that is Nix Olympia, I'm goign to put some effort into the images I have a probably stack multiple sets of AVI's to see if I can pull out more detail, but last night with the high cloud, fireworks and also a warm scope it was not good. So no its not in the observatory at the moment.
The images was LX90 F30 2 100sec AVI 10FPS.

Wow! reprocessed version is superb... Very sharp & loads of details - That's unbelievable seeing it was from your back garden in not the greatest seeing conditions... fireworks etc. It's a real shame you didn't try it at DSC.. Mike RU going to give it a try with your new Vixen...?
Cheers, John
I can't see a difference between the jpeg and the png. What qulity setting do you use on jpegs?
Excellent image Chris. The png looks slightly lighter to me.
Yup JPG looks darker but with a little less detail? Strange.
Anyway, I'd really like to get my paws on a 12" or 14" scope to see what we could get out of mars, or a 5x Barlow (must get one).
I wonder whether the difference you're seeing is the effect of png providing a way of handling display gamma?
