Suavi is correct, they’re hot spots that will largely be removed when you calibrate the data. You’d be best setting up a dithering pattern for the long term though. Although what you have at the moment will statistically remove hot pixels you may end up with a form of PRNU; walking noise. You won’t notice it until you start stacking for longer integrations and it’ll really limit how much stretching you can do for the fainter signals.
G'day Colin. Not sure what PRNU is. Another job for Google.
