Hi all, looking for insight into removing some reflections from my flats.
Two flats below are filters Blue (left) and Green (right), same exposure and gain.
What are those small circles that are consistent in both images? The large circles on the left are dust motes, but both images have the smaller circles.
Flats taken in living room with:
-flat panel, with white paper between C925HD and panel to diffuse light
-room was dim but not dark
-towel draped over OTA vents and imaging train to block stray light
ASI1600MM, ZWO 8 Position EFW, OAG, C925HD
