John Pratte sent this to me recently, and asked that I share it here.......
building a client's 22", I was struck by all the American amateur
astronomers / entrepreneurs who have contributed to the project:
- You made the 22" f/3.3 quartz primary and quartz secondary.
- Carl Zambuto coated them (Note: Carl coats for his clients and LCO, not the general public).
- Gary Myers (StellarCAT) made the ServoCat.
- Roger Greenwood (Astrocrumb) made the filter slide.
- Charlie Starks (Markless Astronomics) made the tablet stalk.
- Rigel Systems made the Quikfinder red-dot zero-power finder.
- Randy Cunningham (AstroSystems) did the secondary holder, dew heater, and shroud.
- Ron Newman at Moonlight supplied the anodized truss poles.
- Ron Keating made the Dewbuster and fan speed controller.
- The scope is collimated with Howie Glatter's laser and Tublug, but also the autocollimator and center spot from Jim Fly (Catseye Collimation).
Feathertouch focuser was originally designed by Werner Schmidt, but
then perfected and manufactured by Jon Joseph at Starlight Instruments.
- And Al Nagler (TeleVue) and Jon Joseph created the SIPS corrector/focuser not to mention the TeleVue Ethos eyepieces that work superbly with modern, faster optics.
- Finally the basic design by John Dobson was tweaked by Ivar Hamburg, Ron Ravneburg, and Dave Kriege among others which brings us to where we are today, large portable telescopes of excellent mechanical and optical quality."
said John. Hope we didn't forget too many. The scope also
features some international contributions including a Nexus DSC from
Australia and a Stellarvue finderscope (imported).
I have to include John in the final item since he has helped evolve the
design of the modern alt-azimuth Newtonians himself, too.
The 22" f/3.3 telescope, with quartz optics made by LCO, is seen below,
and as I write this it is starting to make its way to the southern US
to join its lucky owner. John's wife, Pat, stands with the
telescope, and provides moral support. Lucky the dog is just seen
in the lower left corner - he welcomes visitors.
