John
Pratte sent this to me recently, and asked that I share it here.......
"Mike, after
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).
- The
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."
Well
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.

the Shop".
