Asteroid Pallas

Astrophotos | Home Page
I just had to say I photographed an asteroid, though it's an unimpressive little streak at the bottom right of the picture. Put your mouse on the picture to add labels, or if you don't have JavaScript enabled, click on the picture to get labels.

I meant to take a shot of it just as it was passing cluster M47, but anticipating approaching bad weather I went for it two days earlier. This is taken from my severely light polluted back yard using a IDAS LPS (light pollution suppression) filter and a Pronto 70mm scope. I was surprised to get anything at all because the sky conditions were quite bad. I could even see a spotlight from the Cerritos Music Center a mile away sweeping through the area I was photographing.

The image was created by stacking five 15-minute exposures made on Kodak Ektachrome Elite II (ISO 100) slide film. Because I took short breaks between the exposures, the composite represents about 1-1/2 hours elapsed time.
