A photo on 4/1/2004 of craters inside the larger crater Clavius. The walls of Clavius are just outside the field of view (fov) of the image. A $20 CMOS webcam (VEO Stingray) was modified to make a lunar and planetary camera. The chip has 320 by 240 pixels and is 1.79 by 1.34 mm in size. I used an 8-inch aperture Cave Astrola telescope, and used a Barlow lens to increase the F/No. from 7.8 to 40 - a high-powered view of the moon! This is a 6-image composite made with Registax. |  |
Photo of Horsehead nebula taken 1/13/2004 with a Meade LXD-55 10-inch aperture f/4 telescope, and a Hi-SIS 22 CCD camera. This is a composite image of 32 1-minute exposures made with MiPS. The faintest stars are about 19th magnitude. No filter was used, and the CCD chip is an early type Kodak KAF-0400 with diminished blue sensitivity - thus I use it only for black and white (B&W) imagery. |

Photo of Perseid meteor train - the meteor flashed by above the "AM" about 5 seconds before this frame. I used an image intensifier coupled to an 8mm video camera. This is 1 frame of thousands, and the faintest stars are about 9th magnitude. The strange clumps at the top are clouds. Their edges are bright from scattered starlight, and the centers dark from totally absorbed starlight. The intensifier is a Litton 2nd generation tube, and the lens is F/2 and 5-inches focal length. | |
Photo of periodic Comet 2P/Encke on 11/15/2003 9:08-9:27pm MST with same 10-inch scope and CCD used for the photo above. This is a MiPS composite of 14 1-minute exposures, and the faintest stars are about 18th magnitude. The coma was a faint and diffuse shaped fan with a faint nucleus at the apex of the fan. The comet is in the milky way - numerous stars! The field of view is 0.39 by 0.26 degrees.
<------------- continuation of Perseid photo caption:
(I've been taking intensified video of meteors since 1993, and have perhaps thousands of images of meteors. I have many frames much more interesting than this one, but my frame grabber has not been working for about a year now. This image is just one I happened to have already in .jpg format.) |
