Hi Chris,
Amazing Jupiter image for the afocal technique. It's great that you've captured the GRS.
As Rob says, some RGB alignment would help. In Registax 4 there is an "RGB Align" tab at the "Wavelet" stage. There is a button "Estimate" that does a pretty good job automatically or you can manually align the channels.
Applying an unsharp mask after you are finished with Registax can help heaps too. I use GIMP to do this as it is free but most use Photoshop.
I assume you are processing in colour with Registax. I've been getting heaps better results by splitting the frames into separate red, green and blue bitmaps and processing each colour seperately in Registax. I then use GIMP to combine them, align the colours and unsharp mask.
Mike's tutorial describes how to work with the colours separately:

In this way you can stack the best frames and get the best wavelet settings for each colour rather than for the full colour image as a whole. Sorry to hassle you if you are already doing this.
Take care,
Doug
