Also have a try capturing with FireCapture. Whatever capture software you use, try to avoid boosting exposure which adds noise. If you are capturing full disc easily, look into reducing capture using a Region Of Interest feature to avoid capturing needless black around the sun. This will also write to disc quicker as you're capturing less data (but more meaningful data) and should let you capture at higher framerate too (giving you more data to process with). Same with capturing closeups of solar features... if you capture only the region of interest you can get more data to work with.

PIPP is also handy for some preprocessing tasks to make life easier in AS! or Reg6.

The stacking and wavelets processing often increases exposure in the process (ie makes the result brighter) so you can try increasing the shutter speed (reduce the exposure time per frame) making it look darker during capture on screen, but again this results in faster frames per second which means more data to process. You'll see and understand once you throw a capture into autostakkert. its always best in photography to err on the side of underexposure instead of overexposure as with under you have flexibility to enhance it but overexposure means you clip data and you cant get that back later, its gone during capture.
