The
Stockton Astronomical Society holds an Amateur Telescope Makers (ATM) workshop
each month in the garage at Jeff Baldwin’s house at 684 Pioneer Ave. in Lathrop,
California. This is usually done on a Saturday nearest the Full Moon, and we
usually meet from 10 AM until 3 PM. There is no prerequisite skill level or
experience needed, and the attendees range from brand spanking new to old and
experienced. Telescope projects range from around 4” in aperture up to and
including at least 40” in aperture. Some of us are building telescopes, some
are grinding and polishing mirrors, some of us are repairing telescopes, some
of us are watching, learning and just hanging out. There are individual skills
that participants can harvest off of others, and between all of us we usually
solve any problem facing us regarding telescopes and astronomical optics.
Our next ATM session is Saturday,
August 14th from 10AM to 3PM. We meet at Baldwin’s Shop at 684
Pioneer Avenue in Lathrop, CA. My phone is (209) 594-1894.
Please
enjoy the individual links. This site is a work in progress, so check back once
in a while to see if things have changed. These sites are in order that would produce
a telescope mirror, so you can either check them out in order or jump to
whichever topic you need to see.
