Backlit power switch
Drive Motors – Made in the U.S.A., Pittman® LO-COG™ brush-commutated DC motors offer
smooth, quiet operation and long life. The motor armatures are skewed to minimize cogging
which is required for low speed tracking. Windings are resin impregnated for greater reliability
in incremental motion applications.
Precision Bronze Worm Gear – 32 pitch, 5.625" pitch diameter, 180 tooth bronze gear
manufactured in the U.S.A. by W. M. Berg, Inc. Manufactured to AGMA Quality Class 10
standard, which minimizes total composite error and backlash.
Bearing and Shaft – Stainless steel worm shaft has 0.4375 pitch diameter and is preloaded
with two ball bearings. The worm is made from a single piece of steel (rather than a two-piece
worm-and-shaft assembly) to minimize run-out, which is a source of periodic error.
4 point RA clutch system for no-slip pointing precision
Schmidt-Cassegrain mechanism that moves the primary mirror to adjust focus is supported
by
two pre-loaded ball bearings, minimizing the “mirror flop” typical of bushing focus
mechanisms.
Latitude range: 10º to 60º northern or southern hemispheres
Maximum payload: 65 lb.
