On the left is Thor's Helmet as seen by a Starlight Xpress MX916 CCD camera. On the right is the Celestron CGE 1400 telescope which allowed the camera to have the view. I made many images with this equipment. Currently, I use an Orion Parsec 8300C one-shot color CCD camera.
The goal of this web site is to promote CCD astrophotography by amateur astronomers. I am a member of the Johnson Space Center Astronomical Society (JSCAS) and lead the CCD special interest group (SIG). The JSCAS CCD SIG invites anyone interested to participate with us in using CCD cameras for astrophotography. For more information, e-mail
On the left is the Ring Nebula as seen by my old CB245 CCD camera. On the right is the 32" Newtonian telescope which used to reside in my Danciger, Texas observatory and allowed this camera to have such a view. This telescope now belongs to the Alliance for Astronomy. Many of the older images on this site were made by this instrument. Some of the other images here were made with my 17.5" Newtonian in a previous version of my Backyard Observatory.

G2V-CALIBRATED COLOR
IMAGING
See WHITE BALANCING RGB
FILTERS
for my 2010 AIC presentation on why and how to use G2V stars for
calibrating RGB filters.
In 1998, four of us were pleased to present our development of color CCD astro-image calibration and processing techniques, including white-balancing with Solar-analog (G2V) star data, atmospheric extinction correction, and foreground sky color neutralization. The article also discussed the use of CYAN, MAGENTA, and YELLOW filters rather than the traditional Red, Green, and Blue filters. If you wish to learn more, click here to see the FINAL DRAFT of the article which appeared in the December, 1998 issue of Sky and Telescope. (I updated this draft on May 21, 2000 to reflect an improved method for CMY data conversion)

Most of the color composite images on this web site have been produced using AIP for Windows and Photoshop. AIP is a superb image processing program written by RICHARD BERRY and JIM BURNELL and available from Willmann-Bell. Here is a Powerpoint presentation on the basic steps in making such composites, emphasizing the use of downloaded DSS images: DSS COLOR PROCESSING .'
