I will provide actual astrophotos later when it get darker during the nights in here.

At this point the sensor feels real good and dynamic range is absolutely stunning!!!

It still has the checkerboard pattern due to the pre raw write channel scaling. Unfortunately I'm facing some stability issues with the dark current injector so a permanent firmware mod would be real nice
