Dobsonian telescope is an excellent observing machine. It features
unmatched stability and smoothness of motion. Plus it is eminently
compact and transportable. However, the Dobsonian has one major
drawback -- no motor drive. You have to push it around to follow
what you're viewing. This can get to be a hassle.
But set a Dobsonian
on an Equatorial Platform and experience INSTANT MOTORIZED TRACKING
-- 75 minutes at a time! Wherever you point you are tracking --
smoothly, precisely -- without losing stability, ease of operation
mounted on an Equatorial Platform becomes the ULTIMATE USER-FRIENDLY
Pictures of Dobs on Platforms were taken at various Star Parties.

purchased from us. Great job, Howard!

brother, Bruce, put a variety of scopes on this Platform.

The telescope and optics were made by Richard Wessling. The Platform
is on a low stand to bring the eyepiece (mounted on the yellow mirror
box) up to a convenient observing height. Mr. Wessling says, "This
arrangement works really nicely."

PLANETARY OBSERVING takes on new meaning. During moments of
super seeing, details can be fully studied and appreciated (Jupiter's
belts or Saturn's ring system, for instance). There are no interruptions,
no need to re-center a drifting planet. Spend all the time you want
to make a drawing - without having to touch the telescope.

your Dobsonian is tracking and camera-ready. This important Platform

DRAWING is reaching new levels of excellence and authenticity.
For many observers, recording on paper what they see is a soul-satisfying
activity. Good drawings take time, patience, more time. Here, the
usefulness of an accurate tracking system is obvious.
