Other Telescopes & Optics - Al Paslow Images- powered by SmugMug

Al Paslow Astronomy Collection

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 > I watched a lot of the 2003 Mars Opposition with this telescope as pictured in my back yard in the summer of that year.
This 3.25 inch Jaegers lens is mounted in a homemade telescope.
The instrument yeilds very beautiful images! The mount is an Edmund Scientific from late 1960's or early 70's.

The colorful tripod is from a surveyors transit.

Al-Paslow > 10 inch f-20 Primary Mirror damaged. This was to be a primary mirror for an f-20 Off axis Schiefspigler Telescope.

Al-Paslow > 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.

Al-Paslow > This is an original spherometer made by the world famous telescope and instrument maker "Horace Dall" sitting on a 4.25 inch Pyrex telescope mirror blank.

I obtained this device directly from a former telescope maker in England and have all documentation on this including letters from Mr.Dall himself!

Horace Dall is the co-inventor of the Dall-Kirkham Cassegrain Telescope. Also pictured is a 6 inch optical flat used for referencing the dial indicator on the spherometer.

Al-Paslow > This is a 6 inch Zerodur optical flat with a percision digital spherical micrometer. All part of my collection.

$Al-Paslow > This is an 8 inch optical flat made of Zerodur ceramic glass. I use this flat for making refractor or cassegrain optics. The instrument next to it is a spherical digital micrometer which is accurate to within 50 millionths of an inch !! Al Paslow telescope collection$

$Al-Paslow > 10 inch f-12 Refractor telescope as installed at Mingo Creek Observatory. I use this scope whenever possible!! Outstanding performance!!$

$Al-Paslow > The tailstock of the 11 inch Brashear Refracting telescope at Wagman Observatory in Russelton, PA. This instrument was restored by the AAAP and is a tremendous telescope!!$
