I did a few experiments with different telescopes today and the conditions deteriorated as time went on. Here are are pair Hydrogen Balmer images -- H-alpha and H-beta -- which I took with my 80mm aperture, 600mm focal length refractor towards the end of the session. Click on the image to see at higher resolution (although the resolution is not as good as typical).
