Thank you for this useful reply. I appreciate the description of image building using the glass filters. That makes sense to me. The asteroids seem like an imaging issue that would be difficult to deal with since they are likely near-field objects that are in motion relative to far-field objects. That would also explain some of the trails that one sees if the objects along that trail are the same object imaged over a multi-step process. I figured there had to be a way to get real coordinates so that people could do research but I was not bright enough to push the buttons to find that link and had to use the tool I hate - Snip & Sketch. I have a license for SnagIt and Greenshot on another workstation, either of which is better than S&S but that installation is inaccessible due to hardware issues. Thanks for helping to make it easier to use these images!
