In high school I built a larger refractor with an A. Jaegers 4 inch objective (miss that scope) and I made my first attempts at lunar and planetary astrophtography. Results were anything but exciting. In the early 70's I purchased the 10 inch f/6 Cave Astrola and again gave astrophotography of the moon and planets a go. Some results were pretty good but on the whole I was wasting a lot of time and film.
At the end of 1999 I purchased an Astrovid 2000 astronomical video camera. This further improved my results as the Astrovid has manual controls for shutter, gain and gamma along with a larger, more sensitive CCD chip. Both my telescopes have proven to be excellent for video imaging as the images below demonstrate. The Intes-Micro Alter 603 f/10 Maksutov-Cassegrain was purchased in early 1999 and has proven to be an outstanding performer for it's modest aperture and compact size. In early 1999 I helped to establish the VIDEOASTRO
E-mail discussion group along with Rod Mollise and a few others that had
been clouding up the waters of the SHALLOW-SKY list with discussions on
video imaging. Shortly after I established the VIDEOASTRO
web site which I still maintain. The VIDEOASTRO group has been largely responsible for my rapid progress in developing video imaging techniques and image processing skills. The group, now numbering over 500, represents a significant number of countries in the Americas, Asia, Africa and Europe. Many members are veteran video imagers along with several valuable video professionals -- the list is a wealth of information. Thanks guys! All imaging with the Astrovid is done with eyepiece projection using either an 18mm Ortho or a 21mm Plossl. Video is recorded to a Hi8 video camcorder, frames are captured to computer with a Snappy frame grabber and image processed with Adobe Photo Shop. |
