Hi, I got this camera few days ago and I've been testing it since then.
Regardless the subject I am imaging, I am noticing always the same red noise gradient on every image. Can someone explain to me what is it? Because at first I thought it was due to the usual pollution gradient, however, even after changing the subject, the shape, size and location of this gradient is mostly the same, even after rotating the camera, so I assume the issue is on the sensor itself.
I attach a few images of different subjects, just stacked using AsiAir Live feature (60 sec, from 10 to 30 shots), dark frame was used, cooling to 0°, no further elaboration was done on the images. From a polluted location, Optolong L-Extreme filter was in place. Telescope is a Sharpstar 76EDPH, no reducer.
