Im thinking of have a shot at a night time terrestial IR photo composed with the sky in the same shot. The 87 filter I have, as shown in the attachment, shows it neatly cuts Ha out, so I can only hope for some exposure from stars fields and galaxys, being broad band scources. Has anyone tried an astro pic with a IR filter?, Is there enough IR light from stars thru the atmosphere to register an image?. This filter is very dense, and results in greyscale only with a modded DSLR. Im also assuming IR radiation from plants and trees in total darkness would produce an image , I havent seen examples taken at night with it.
