I'm trying to stack 99 light frames (RAW files from a DSLR) of a very, very tiny Saturn. When I stack them, they all just "smudge" the Saturns across the screen.
Examples below:
One raw frame:

After stacking:

How can I get Registax to actually "align" the images so that I only have one Saturn?
EDIT: Also, is there a way to zoom in to say, 200% or 300% in Registax? It would make processing a bit easier when my target is so small.
FWIW I've tried using Ninox however I'm finding it very difficult to use.
