Thumbs up cat-cooled JUPITER May 9th

Hi All,

Got my new Lymax Cat Cooler yesterday and tried it out last night. Not that I have any real idea how to use it, I just left the scope out for an hour then bunged the cooler in for 20 min prior to imaging.

Seeing was fairly good, around 7/10 and slowly improving I think, but I had to pack it in around 10pm to get some kip for work next day.

Anyway seeing was good enought to warrant breaking out the 4x powermate. Prob my best avi was the latest of the night (more evidence that the seeing was improving). Here I've shown this image with three levels of processing, ME deconvolution, ME and Unsharp Masking and finally an LR deconvolution with a bit of median filtering to reduce grain.

I'm prestty happy with the result. I also have attached a scaled down version as it sharpens things up and again reduces grain.

cheers,
