Autostakkert keeps producing these artifacts on Jupiter.

upon playing around with it a bit more, it seems it is a problem with the APs. The bigger I make them, the less artifacts there are, but they are still there. Please help.

What gear are you using to make recording?

These artifacts are because of compression in video. In order to make clear image you need to record raw uncompressed video instead.

I am not sure these are compression artefacts. I sometimes get these at times of bad seeing. I would in any case start by adding RGB alignment, which does not seem to be switched on. Furthermore, trying various sizes of APs helps, as does reducing the the percentage of images to stack. Sometimes it helps to first process in PIPP, to do an initial alignment of the frames and a coarse selection of the frames to stack

It has already been run through PIPP, will try the RBG alignment, normally I do it in registax but I have never had this problem before, the seeing was alright too.

What was the gain set to at capture time - high?
