My R filter is producing some really bizarre artifacts, hopefully highlighted the below gif.

A couple observations:
  • Only the R filter is having this issue
  • Filters are in a FW
  • Issue doesn't show up in my R flats, or darks


Below is a Blink output of a selection of 10 subs, 300s.



Any ideas? Could the FW be slowly rotating during the subs?

Cheers,
Omar

Did you set the filter wheel to move in one direction? Could be backlash in the EFW motor.

It's not set to move one direction no. I'll try that and recapture.
Thanks for the sanity check!
