Bob and Janice image with a 12.5-inch Ritchey-Chrétien Cassegrain telescope built by Parallax Instruments and an 8-inch f/4.5 Newtonian with Discovery optics built by Tony Hallas. They’ve just begun experimenting with an SBIG ST-10XE CCD camera. Prior to this, Bob and Janice produced images on film, using a Celestron 11-inch Schmidt-Cassegrain telescope.
