Comet Tempel at 4 realizations

Comet 9P/Tempel 1 on 04/21/2005 from 05:49 to 07:05 UT. A composite of 240 fifteen-second exposures (a total exposure of 60 min) with the Meade DSI 1-shot color CCD camera and a 10" aperture f/4 Meade LXD55 Schmidt-Newtonian telescope. The fov for each image is 16.6 by 12.5 arc-min; with north up and east to the left. This photo was taken under a 12.4 day-old moon only 24 degrees distant. (I was the 1st STSP contributor to image the comet under a nearly full moon, and others are now doing the same.)

This is my home page, and I began site construction on Dec. 2, 2004. Thanks to the ease of use of this site builder (Trellix), everything has assembled fast; but how long I keep this site depends on many factors - it could terminate for a number of reasons (some beyond my control). You can find me if you Google on "R. B. Minton ALPO", or write me at 568 North First Street, Raton, NM, 87740 (USA). I am the ALPO Instruments Coordinator (Association of Lunar & Planetary Observers).

The photo at right was taken 6/2/2004 with my 8-inch aperture f/7.8 Cave Astrola Newtonian telescope using a Logitech Quickcam Pro 4000 webcam. Thirty-one video snippets were taken - each lasting from 20 to 60 seconds; and a total of about 19,000+ frames were taken this day during a 2-hour interval as Venus was high in the daytine sky. I chose the best 5 to make the final image shown here. The resolution is very close to the best possible with an 8-inch aperture - about 1/2 an arc-second.

This web site will illustrate the variety of instruments I have built, their use and performance; and my underlying love of all types of scientific investigation. These sciences will include astronomy, physics, optics, photography, and electronics.
