You should!I should try this!
I use similar technique for photographing places without people. Just take several photos of the same place and because the fleshy blobs of annoyance are the only thing that tends to move, it's easy to tell the software to remove them in the stacked image.![]()
You need to align the sub images so that the stars are exactly on top of each other. You can do it manually in Photoshop etc, but normally software for astronomy photography has a function that can do that. When I get to the next nebula on my trip to the edge of the galaxy, I'll try to make an image containing much more subs (50-100). If you let the camera drift slightly, you should be able to remove some of the "banding" you see in the image I posted, which is caused by the dark areas of the image being gained (amplified) and the low bitrate of the screendumps (8-bit).
Do you use difference keying for your images?
Edit: @Chris Simon: The idea about removing people from crowded places is excellent!
