I have a brand new ASI2600MM Pro. On my second use I experienced strange writing errors on all of my subs. See attached photos. First, there are grainy horizontal line patterns everywhere. And if you zoom in on the stars you see that on the "bad" lines the pixels appear to be shifted over. The right data in the core of the star is shifted several pixels to the right.
I shot some new darks of same exposure duration (300s) immediately after this to see if the lines appear there as well, and they did not appear on the darks.
Any idea as to what is causing this?
