Chris, that's a perspective I hadn't thought of, but may be able to make use of. The angle I was approaching this from was... well, when I started in astronomy, I star hopped to objects (who does that any more?). To do that, I had a piece of cardboard with a hole that matched the FOV of the scope or finder for the star chart I was using. Pretty much the way everybody did it, I guess. I was thinking that if I could create the "piece of cardboard with a hole in it" in stellarium, I would be able to see potential targets as they came into the "viewing area." Somewhat doable, but not easy.
