I know this is hammering on a flush nail, but I’ve discovered some interesting differences between Hartmut’s FLI ascom FLI driver and the SGP FLI driver.
I was rather disappointed when my sensor had a section halfway down to about 2/3’s down with diagonal banding. No other defects. FLI could not see this noise when they had my camera for shutter repair. I thought it was electrical noise related to somewhere in my hardware and went so far as to isolate date and power cables and added ferrite cores. The problem persisted.
I have only ever used SGP with my FLI camera, but I’ve recently started using Hartmut’s ascom driver, and the problem went away.
