Brad, like many of the great astroimagers that push technology to the edge and their craft into regions unheard of even just two years ago, has contributed the following four tricolor images of planetaries that he recently imaged. His web site, was appropriately named 'ccdimaging.com' (as of August, 20001, I can't find a link to Brad's new site, if any), is an Internet treasure for the variety, quality, and depth of his images. He has imaged galaxies of almost every variety, emission and dark nebulae, globular clusters, and of course planetaries.
The equipment that Brad uses for his imaging includes a 12.5" f/9 Ritchey-Chretian telescope on a Mountain Instruments GT1100 mount and an SBIG ST-8 CCD camera, equipped with the SBIG AO-7 Adaptive Optics assembly. As of the end of 1998, he is in the process of moving his observatory from Lake Tahoe, California to a location near Flagstaff, Arizona.
