Date: May 28-31, 1993

Attendance: 1,557

Attendance was down a little with the First Quarter Moon, but the Telescope Field was still bristling with activity. A new size record was set by the Valley of the Moon Astronomical Society (VMAS) with their 40" F/3.2 Dobsonian. The primary mirror, which is just 3/4 inch thick at the center, was ground by Harold Moore. It rests on a 114-point flotation system and weighs just 110 pounds.

A mechanical marvel was the 24" F/4 made by Jim Hannum. It has a wonderfully machined equatorial mount and a foam core fiberglass tube. It weighs 660 pounds and requires three people to assemble.

Gerry Logan checked in with a 12" F/15 Maksutov which gave wonderful images. He incorporated a new thermal equilibrium system that steadied the image within 30 minutes.

John Dobson provided an impressive telescope making demonstration. Along with a group of volunteers, he created a 10" telescope from a pre-curved mirror blank an a pile of wood. The uncoated mirror provided good views of the Moon before the evening program.

Finally, this was the 25th RTMC. A celebration honoring Cliff and Jackie Holmes and the RTMC, complete with cake was held Saturday Night. Clifford W. Holmes passed away three months later.
