I've processed another mono Saturn capture from 8/3/11.
CPC11 (Alt-AZ), DMK21AU, 2x barlow. Seeing about 7/10.
Best 1247 of 2546 frames processed in Registax 5.1.
I'm happier with this one. I reckon its a lot better than my previous one. The rings are clearer than my other capture/process and the storms visible too. Any advice/thoughts?

Tony, very nice image to capture some ring detail there. Are you stacking via centre of gravity in Registax?
I tried some imaging on Jupiter last year but found real issues with "onion" rings in my image which was explained by fellow members as compression artefacts. So the quality of the image had a lot to do with the compression from the CCD device but not sure exactly the details.
The percentage of frames stacked sounds about right. You will find that RegiStax will work better if you do some work on your data prior.
You could try using Castrator to centre, align & crop your avi prior to Regi or you could run your avi through VirtualDub, converting your avi to bmp files, then run the output files from VD through ninox to align, crop, renumber and do a quality estimate. The output from ninox will then have rearranged and renumbered all of the bmp files from best to worst. You then only load the best 50% of the bmp files into Regi and process & stack the lot of them. You should put in quite some effort to make the best possible reference frame, a stack of 100 to 150 frames should do the job.
