Exactly what must have happened! I opened in photoshop and the sudden changes disappeared! Thanks very much :).

Hi, Newbie here. I'm in the process of doing some backyard astro-photography with a canon 600D. When I load the images from the SD card on the PC they look normalish (this doesnt happen with the pictures I took earlier but I realised they were in jpeg and not raw format). Then 1 or 2 seconds later the image gets digital interference. Any thoughts? Would welcome any other thoughts on improving the 'before' image too. 🤣 Thanks!
