Is it possible to get reflections in the imaging train when using NB filters? I got a couple of new NB filters and seem to be seeing reflections in the image from the reducer.

This S2 image is a stack of 20minute subs shot at x2 binning. If it is a reflection it's also in this single Ha shot. I didn't know they where there until I did a ddp stretch on the images.

Concidering how difficult it is to get any data from an S2 filter, it seems odd to have reflections like this. When it stops raining I'll try again and rotate the camera to see if it moves.
