Visual Use
For dual-purpose photo/visual scopes, a "VISA" adapter (Visual / Imaging System Adapter) accepts the tunable top from the standard Tele Vue 2" Paracorr Type-2. The 2" format is fine visually since secondary mirror size limits maximum exit pupil diameter to around 7mm. The widest true field eyepiece choice with an f/3 (f/3.45 when used with Paracorr) is, therefore, Tele Vue's own 21mm Ethos which delivers a 6.1mm exit pupil at f/3.45.
Imaging with DSLR or CCD Cameras
If you have a 35mm format DLSR or CCD camera, the "VISA" adapter accepts Tele Vue Imaging System accessories.
$450.00
This adjustable-speed, electric motor-drive installs easily onto the Focusmate unit, and offers a unique quick disconnect for switching (without tools) between electric and manual operation. Variable-speed, forward/reverse, battery-operated hand-controller is included.
With the exception of the TV-60 (non-"is" version), all current production Tele Vue scopes accept a digital Indicator Kit -- so that their fullest imaging and visual performance can be realized. If a digital Indicator Kit, is installed, measurement is possible to an unprecedented 0.0001" (1/10,000"). A gentle tap on the motor direction switch can produce steps as small as about 0.0005" (5/10,000"). Truly, focusing will be "even better than you imagined."
Models available for 10:1 Focusmates (all black) and left or right-side mounted 6:1 Focusmates (chrome shafts).
- Vibration-free motor-drive unit
- Two-button hand-controller with variable-speed knob
- Motor-ring mount, with quick disconnect and focuser mounting instructions
$350.00
As you've read, all Newtonian / Dobsonian telescopes can benefit from using a Tele Vue Paracorr (Parabola Corrector) to eliminate coma in the image. One aspect to optimizing this correction is the distance of the eyepieces focus point (field stop location) to the last surface of the Paracorr lens (within a small +/- tolerance of course). Typical eyepieces used with fast Newtonians can have field stop locations differing by as much as half an inch. To accommodate for the differences, we developed the "Tunable Top."
The "Tunable Top" permits optimized aberration control for all Tele Vue eyepieces and many others, by simply loosening a screw and rotating the Tunable Top. The eyepiece barrel height raises and lowers, allowing you to maintain the proper field stop to Paracorr lens distance.

Tele Vue BIG Paracorr - Type 2 (3inch)
Tele Vue's 3" BIG Paracorr Type-2, designed by Paul Dellechiaie, extends the Paracorr type 2's optical benefits for imaging applications by amateurs and professionals using CCD formats as large as 52mm diagonal and paraboloids as fast as f/3. Back focal length has been extended to 80mm to allow for additional accessories to be placed in the optical path. The 5.1" length optical assembly is topped with a "stop" flange having 3.40"-24 pitch threads to mount camera adapters and spacer tubes (available later).
Paracorr Eats Coma
Paracorr can be used with both 2" and 1¼" eyepieces. For visual use, slip Paracorr Type-2 into your focuser like a Barlow lens, and your eyepiece into Paracorr. (3" BIG Paracorr Type-2 requires adapter and tunable top for visual use). 1¼" eyepieces will make use of Paracorr's special low profile 1¼" reducing adapter. Paracorr is threaded for 2" filters.

This 2" to 1¼" adapter allows more in-travel for 1¼" eyepieces than our "flat-top" or "high-hat" adapters. This adapter is designed to attach to the 1¼" eyepiece barrel and convert the eyepiece for use with a 2" focuser or diagonal. The main application is for 1¼" eyepieces that may need more in-travel due to limited focuser range of your telescope.
The "In-Travel" model achieves the following amount of in-travel benefit compared to our conventional 2" to 1¼" adapters.
hese adapters allows use of 1¼" eyepieces in any 2" focuser or diagonal.
All models feature brass clamp ring or nylon-tipped set screw for secure, no-mar locking and safety undercut.
Note: We purposely do not put 2" filter threads in 2" to 1¼" adapters. The reason is to avoid your getting upset when you insert a 1¼" Barlow and it crunches your expensive 2" filter. Safety first.
$130.00
"Flat-top" model
A flat-top model allows closer placement of the eyepiece. Use with Newtonian reflectors, Tele Vue Paracorr, 2" Powermate, and 2" Big Barlow.

Tele Vue Equalizer 2 Inch - 1.25 Inch Adapter
Equalizer model
A heavy solid bronze version called the "Equalizer" adds 12-ounces to help equalize the weight when switching from heavy 2" eyepieces to light 1¼" eyepieces. Features exclusive anti-reflection angle that prevents reflection back to the objective.
These adapters allows use of 1¼" eyepieces in any 2" focuser or diagonal.
All models feature brass clamp ring or nylon-tipped set screw for secure, no-mar locking and safety undercut.
Note: Tele Vue purposely do not put 2" filter threads in 2" to 1¼" adapters. The reason is to avoid your getting upset when you insert a 1¼" Barlow and it crunches your expensive 2" filter. Safety first.

Tele Vue Eyeguard Extender, Twist-on Style
Eyeguard Extender raises the eyeguard position by 8mm, and includes a rubber eyeguard and eyepiece cap (in case yours is lost or damaged.) Units are stackable: for example 2 units add 16mm height and make a 40mm Plössl very comfortable for solar viewing by blocking out stray daylight to maximize contrast in white light or hydrogen-alpha viewing.
Eyeguard extender is black anodized aluminum with anti-reflection threads.
The Eyeguard Extender attaches to the top of your eyepiece with the simplicity of a DIOPTRX™ corrector. It has two rings that thread together to clamp on the eyepiece: an inner-ring that holds the rubber eyeguard and outer ring that slips over the top of the eyepiece. Starting with the inner-ring backed off from fully tight, take off your existing rubber eyeguard, place the Eyeguard Extender in its place, screw-down the inner ring until the Eyeguard does not slip off.

Tele Vue extension tubes slip into any telescope's 2" drawtube and include brass clamp rings to prevent marring of accessory barrels.
$670.00
Model TRF-2008 Tele Vue 0.8x Reducer/flattener 400-600mm converts TV-85 to 480mm f/5.6 and TV-76 to 380mm f/5.0 for flat field, fast photography. Fully multi-coated 3-element unit inserts directly into 2" focuser, accepts standard T-rings for 35mm cameras. Whilst designed for use in the TV-76 and TV-85, it can be used with other fast refractors between 400mm and 600mm focal length.
Used in prime-focus imaging, reducers increase photographic speed while flatteners decrease image curvature away from the center.
Important Note: The following products were all designed for an optimum 55mm back focus. (Distance from flange surface to film or CCD plane). If you use a CCD, be sure the spacing between flange and CCD is 56mm +/-2mm for best results.
"This accessory is a must-have for someone planning to use the TV-85 photographically" - review in Sky & Telescope, July 1999. Also it can be used with any 400-600mm refractor.

Optec Gemini Focuser Rotator
Temperature Compensation:
Like all Optec focuser products, Gemini includes a remote temperature probe for automatic temperature compensation. Simply attach the temperature probe anywhere in the linear response zone of your OTA (usually the tube or truss assembly) and Gemini will automatically keep the camera package in sharp focus. The Gemini Commander software provides a convenient wizard to help determine your telescope's TC or temperature coefficient.
Robust Compact Design
Support for Multiple Telescopes
Featuring identical OPTEC-4300 mechanical interfaces front and back, the Gemini can be easily fitted to most any large telescope OTA. Recessed oval point setscrews provide three-point direct contact with the heavy wall OPTEC-4300 dovetail mount. Gemini's clear aperture of 3.75" is maintained through each adapter, passing even large light cones through to the camera image plane without vignetting.
On the camera side, a typical configuration might include a 4300 receiver for the Optec-DSI 3.5 High Performance spacer sets configurable to 1/4" increments when additional spacing is needed.
Currently designed telescope adapters include support for the AG Optical iDK's, Ceravolo Optical Systems Astrographs, Meade and Celestron 10-inch and larger class SCT, and Plane Wave Secure-Fit.
Multiple Ways to Connect:
The Gemini Control hub acts as the central controller to link both focuser and rotator to any control PC. The hub includes communication ports for Serial and USB (using Optec's USB/Serial cable) and wired Ethernet Network protocols as standard. An optional WiFi board and antenna can be added and installed at any time. Focuser and Rotator ports are available at the top of the Gemini hub with 12VDC Power, Network, optional Hand Control, and Serial connection ports available at the bottom.

Optec Temperature Compensating Focuser-S3i
No corners were cut with this model. The massive drawtube has a 3.00-inch I.D. and is made from 7075, the strongest of the commercial aluminum alloys. To prevent any slippage common to Crayford style focusers, the drive rod is pressed onto the drawtube with a force of about 500 pounds. The TCF-S3 can take this extreme pressure because the drive rod is made from a ground bar of high speed steel with a diameter of 0.375 inch. Hardened rails of stainless steel are embedded in the drawtube to engage the drive rod and take the strain.
TCF-S3 with gear cover removed. All gears are made from 303 stainless.
The total linear travel of the drawtube is 1.00-inch with a resolution of 0.0001-inch. Like the TCF-S, a control box with IN and OUT pushbuttons, serial computer interface and digital display control all functions of the TCF-S3. All other features of the TCF-S3 are similar to the TCF-S. It uses the same cables, temperature probe and the new remote keypad. It is also compatible with the current Optec control software TCF-S.exe.
Other telescope mounts can be made custom in our shop. This focuser is only intended for large scope with massive mounts. See price list for a list of available mounts. A 3-inch to 2-inch adapter is available to fit Optec and other standard 2-inch accessories.
TCF-S3 with standard accessories that include controller, temperature probe and power supply (not shown).
For owners of the Paramount ME, Optec offers a special kit that can conveniently wire the TCF-S3 through the mount. In addition, both the IFW and Pyxis can also be mounted and wired through the mount for easier use and less cables.
