Strange pattern with ASI071 MC-Pro dark frames

muratsana

I am having strange pattern with my brand new camera with dark frames as seen in the screenshot. All calibration frames are taken with pre-defined HDR Gain (-15c) at several different exposure times. All master dark frames have this pattern as i noticed. (120 - 180 - 240 seconds)

Single dark frame and master dark frames can be inspected from this link:

Any ideas what causes this pattern?
