Images and events of personal interest.
I have owned, made and acquired various instruments over time. I've made the optics to a number of reflector telescopes over the past 35 plus years. Most of the homemade telescopes were given away or sold for a very reasonable cost. I don't have many pictures of the old instruments. At this time I own several Jaegers refractors, a Cave and a large Star-Liner and the neat little Palomar Jr. They are listed under seperate Galleries. I have other homemade instruments in various stages of completion and some that are in use. The largest project is a 16 inch f-5 f-20 Newtonian Cassegrain I have been building for more than 15 years. The optics are done, but everything is so expensive it still will be a number of years till the telscope is finished to my satisfaction. This Gallery will show some optical testing equipment, the old folded Buchroeder off axis mirror, a Horace Dall spherometer, etc. Also you can see other telescopes I use on occassion and they are interesting to see too. More to follow!!
Al Paslow, and my 10 inch f-20 primary mirror for a Buchroeder reflecting Schiefspigler Telescope.
I broke this mirror in the early 70's while attemping to remove a small central zone during "hot pressing" the mirror on the pitch lap. I slipped on some water on the floor and broke a section from the mirror trying to place a heavy weight on to the combination. I made this mirror shortly after this particular design was sent to me directly from Richard Buchroeder, in 1971. It was a modification of the design which appeared in Sky & Telescope Dec 1969. The modification was called O'Neil- Buchroeder Schiefspiegler" and no one had compleated an instrument of this type. This mirror might well have been the first.
