This shot was taken using a 500mm f/5.6 Maksutov-Cassegrain attached to my lightweight equatorial mount using a 1/4-20 adapter that was bolted and taped to the mount's top plate. A Pentax K1000 was attached to the Mak-Cass. The Mak-Cass was focused using my MFFT-55's Ronchi grating prior to attaching the K1000. This was an unguided exposure and it lasted for 2 minutes. It was taken on 2/8/97 at 5:55am PST. Polar alignment was done by sighting along the right ascension axis of the mount.
