They are in all my frames in the exact same position.   It is from the Meade DSi 4. I told Meade I would hold off exchanging the camera pending resolution of some issues but I just now realize these dark spot artifacts are all in the same place. Very odd.

Why are thinking of returning the camera? I’ve been curious about the new DSIs.

Have you isolated the dark spots to one part of the imaging train?  I.e. if you rotate the camera, do they rotate as well?  It could simply be some gunk on a lens or filter element.  This should be easy to narrow down...

oh right so if i rotate the camera and it shows up in the same sport then it is the camera somewhere I presume?

If the spots rotate with the camera, it is the camera that has an issue.  If you rotate the camera and they do not move it would be somewhere in the scope or filters.

Think this is likely on the camera looking at how close it is to the sensor but rotating the camera will confirm this.

i was sure that was the correct answer but i was also thinking some form of lethal blood sucking bats. or moth man.  I once met a man at a dark site who insisted that he observes mothman with his infra-red binoculars. He had a following with him to. So I am thinking maybe that is the same mothman...
