Good afternoon, some time ago I bought your equipment, a camera like this 533mc pro, lately I get a horizontal noise pattern that I don't remove with the darks, it even seems that they are accentuated over time, I don't know what it could be, since it always I do the same process, I haven't been involved in astrophotography for a long time and it has me a little lost.
All the best.
Thank you
