These kits include everything but the optics. Shoot us a call or Email to help you decide what will work best for you!

Why the TeleKit is the most advanced truss telescope on the market.

1.  QuickSwitch Filter Slide.  The four position slide makes it a snap to change filters with a twist of the control knob.  No more removal of the eyepiece and thread mis-match.  One of the most powerful observing aids is now at your fingertips. It is that quick, easy, and SAFE!  *NEW* The filter slide has been modified to be compatible with 2" Bino-viewers and laser collimators to protrude through the slide for proper function.  Thousand Oaks and TeleVue nebulae filters are available through AstroSystems.

2.  Focuser:  The JMI EV-2 focuser is standard on the TeleKit.  It features precision roller bearings, Crayford no backlash friction drive and has smooth focusing at high power.  The Feathertouch focuser with two speed 1:1 and 1:10 reduction and compression rings in both the drawtube and adapter is a $269 option, the Moonlight focuser is a $69 option.

3.  Upper Truss Fastener:  Easy cam action.

4.  Lower Clamp Fasteners:  They are positioned inside the mirror box for an uncluttered look and are strong and precise.

5.  Finger Jointed:  Both the rocker box and mirror box are constructed with finger jointed Baltic Birch plywood, durable and solid.

6.  Altitude Bearings:  Ultra smooth large radius bearings that move on one Teflon and one ball bearing per side.  Drive and DSC compatible.   Fingertip motion and complete control of resistance.

7.  Mirror Cell:   The easy access tailgate assembly allows quick access to the primary mirror.   Just remove the two bolts to drop down the mirror cell to clean or remove the mirror.  This makes installing and removing the mirror much safer, especially for large optics.  The mirror transport system protects the primary mirror and flotation assembly by supporting the primary mirror on cushioned pads.  The stainless steel sling insures accurate collimation by maintaining the primary mirror position.  With hundreds of TeleKits in the field, this support method has proved to be the optimum method of primary mirror support to achieve the best planetary resolution and deep-sky images.

8.  Azimuth Bearing:  Three sealed ball bearing sets riding on stainless steel axles.  Low maintenance and zero backlash.  The adjustable brake is standard.

9.  Truss Tubes:  Telekits are supplied with 6061-T6 seamless aluminum trusses.  They are protected with a black, heat shrink protective coating.  The light shroud, a $100.00 option with most truss telescopes sold, is a TeleKit standard feature.

10.  Upper Cage:  The upper cage is light, strong and can be stored fully or partially (12.5", 13.1", 14.5", 15") in the mirror box.  This feature provides safer and more compact transportation.

11.  AstroSystems Spider and Secondary Mirror Holder:  This time tested assembly is rock-solid and has four collimation screws (thumb screws for 3.1" and up) for fast, easy and precise collimation every time.  Compatible with AstroSystems Dew Guard.

12.  Stainless steel hardware:  Stainless steel is used throughout with the exception of some internal fasteners, providing strength and corrosion protection.
