Help request: odd artifcats in darks and lights
Hi guys. I'm getting to grips with a QSI683wsg and finding it a real mixture of good and puzzling. The biggest concern is the appearance of these odd short streaks of light in my darks and lights.
I attach 3 images. Two are from different darks and one is from a light - all 10 minute subs at -20C.
In the darks, you'll see random short streaks of light - not entirely linear, not columnar and not horizontal either. And you'll see the same sort of thing repeated in the light frame.
I've switched the whole imaging train across to another pier with a different USB hub, different PC and different power supply. These artifacts continue to appear.
They do not repeat in the same location. They appear to be randomised but persistent.
Perhaps a symptom of the same underlying problem, there seems to be an inordinate number of hot pixels as well.
Can anyone with KAF8300 experience (or QSI experience) throw any light on this?
Peter
