Tom Osypowski Equatorial Platforms

Equatorial Platforms is collaborating with Kennedy Optics in the manufacture of large, low profile All-Aluminum Telescopes with a choice of formats:
1) the SpicaEyes Telescope System with integrated Aluminum Platform and 2) the SpicaEyes Telescope System with our new SlipStream Drive.


SpicaEyes Platforms

Toms SpicaEyes Platform Drive Telescopes
Large-apertureAluminum Telescope on an Integrated Aluminum Equatorial Platform

This is a complete telescope system. Find an object fast with the Digital Setting Circles, then keep it centered with the tracking of the Platform. Use high powers to enhance the view. Grab the scope anytime to move around and explore a new area - there are no clutches to disengage. The optional Dual-Axis Platform provides the controls for astro-imaging and auto-guiding. There's no field rotation to worry about.

Features include:

  • Rocker- and mirror-box are welded, box aluminum structures (light in weight, yet extremely rigid).
  • 18- and 27-point mirror cells with fans, switches, and battery installed. 4-point floating edge support for stable mirror placement; no sideways shift.
  • Upper cage rings are manufactured from a high-tech aluminum/plastic composite - lightweight, thermally stable, and very flat.
  • All aluminum components are powder coated or hard black anodized. Stainless steel fasteners are used throughout.
  • Primary mirrors are of highest quality. Each one is rigorously star-tested before shipping as a final check on its figure.
  • Renowned Starlight Feathertouch focuser is standard equipment.
  • Sky Commander DSCs are standard (Argo Navis DSCs available as an option).
  • Telescope comes complete with an integrated Aluminum Equatorial Platform in the Compact format. (Upgrading to a Dual-Axis Platform is an option.)
  • A full shroud is included
  • Tight fitting front and back covers for the mirror box provide excellent protection for the mirror during transport and storage. Also, nylon screws can be tightened against the edge of the mirror to prevent any sideways shifting of the glass during transport.


SpicaEyes SlipStream
Large - Aperture Aluminum Telescope System with SlipStream GoTo  Drive

These new SpicaEyes Telescopes combine solid All-Aluminum construction with a new GoTo drive system that integrates a Slip Clutch on both axes for full-time manual and motorized slew control.

You can find objects fast by using the included Argo Navis computer. The telescope will automatically slew, or you can move it by hand. Once you find your target, the telescope will track it for you, keeping it centered in the field of view. The integrated SlipStream clutches allow you to move the scope at any time by hand or with the motorized slew control, with no levers to disengage.

Shown to the left and below is a 28" f3.66 SpicaEyes SlipStream Telescope. The oversized altitude bearings sit on 1"diameter stainless steel shafts rotating in pillow block ball bearings. Both axes are driven by Servo motors through a stand-alone computer mounted to the telescope. The adjustable slip clutches are fully enclosed and protected in a metal housing. Thumbscrews allow one to adjust the drag of the clutches as needed.

A wireless hand control gives three-speed slew control on both axes. The fast slew will spin the scope completely around in less than a minute, useful for going across large stretches of the sky. The medium slew will nicely center objects in the field of view at low and medium powers, and the slow slew will do the same at high power. All three slew speeds can be individually calibrated to the user's requirements


  • Welded Aluminum construction using stiff rectangular tubing and solid plate or bar as needed. All metal surfaces are powder- coating or anodized for long-lasting durability and beauty.

  • 18-point welded steel mirror cells with fans, switches, and battery installed. 4-point floating mirror edge support. Nylon locking bolts prevent mirror shift during transport.
  • Primary mirrors of the highest quality. The 22" to 32" mirrors are from Kennedy Optics.

  • The short f/ratios of these exquisite optics make for a low-profile design with no compromise in image quality.

  • Servo motor GoTo Slew and Track system, with built-in slip clutches that allow manual movement of the scope at any time. All of the drive components have been designed and manufactured by Sidereal Technology.

  • Argo Navis computer and hi-res encoders are included, as well as a convenient stand for the AN computer.

  • The renowned FeatherTouch focuser is standard.

  • An AstroSystems shroud is fitted to the truss poles.

  • Tight-fitting front and back covers for the mirror box provide excellent protection for the mirror during transport and storage.

  • Convenient handles and wheels are provided for easy transport of rocker/mirror box assembly.

  • A rotating upper cage is available as an option.

Webster Telescopes has always had one goal in mind, BIG, PORTABLE DOBSONIAN TELESCOPES!  While other manufactures were removing the large telescopes from their product lines, we were adding even larger ones to ours.  The big Dobsonians are our forte.

But, just making the largest telescopes is not enough of a goal for us.  Making Ultra-premium telescopes, unmatched by any commercial scope manufacturer, now that's a goal worthy of the Webster family name.  Now in our 4th generation of woodworkers, Webster Telescopes really can claim to combine Old World craftsmanship with today's Computer Aided Design.

Having a giant telescope would only be half the fun if you could not take it with you.  Our telescopes were designed right from the start to break down into an easily transportable unit.  Our users report that they can set up a Webster Telescope in 10 minutes, all by themselves.  You will be aligned and viewing while the other guys are still leveling their tripods.


Our new "C" series of truss telescopes exclusively feature Kennedy Optics telescope mirrors.  These "fast" mirrors have taken the astronomy world by storm, especially for those who have an obsession for textbook Star Tests.
