Hi guys,

I was wondering if any of you had what looks to me like interference bands on a modded 900NC webcam? I tried using it lastnight and the bands appeared in all frame rates and they are just a pain for trying to find guide stars. The bands are equal in distance apart and run horizontally across the FOV.

I was thinking maybe a ferrite ring around the USB lead near the computer side?
