<< You will probably capture more meteors using a standard 50 mm lens
rather than your 28 mm wide angle. I know that a wide angle lens seems the
way to go but the aperture of the lens is more important than the wide field
coverage. Our 180 degree Sandia All-sky camera will only record meteors
brighter than -2.5 - -3.0 magnitude where a 35mm camera with a 50mm standard
lens will record +1.0 meteors. Also the image scale is larger so the
recorded meteors will look nicer. I use Tri-X 400 ASA film as a standard
for spectroscopy. >>
