Tele Vue Spacer Ring Set of 6

Focal Path: Extension
Focuser extensions of various lengths are often used to create the necessary distance for proper spacing of field lenses to imager; the required distance will vary depending on camera specifications. All are black anodized aluminum with anti-reflection threads for maximum contrast.

Set of 6 Accessory Tubes is a complete set of the tubes/spacers described above. This allows great versatility in achieving the necessary distance for proper spacing of field lenses to image plane.

Tele Vue TV60 Carry Bag

Our custom telescope bags allow convenient and stylish transportation of your Tele Vue telescope.

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.

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

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 Mounting Ring Set 5 Inch

Our ring sets provide rigid mounting for astro-imaging with our 4" and 5" scopes. Bottom and top of each ring is drilled for ¼”-20 hardware, have bat-handle locks, and two Tele Vue accessory slots for ring-mounted accessories such as Starbeam with Tele Vue base, Sol-Searcher, Piggy-Cam and others.

Sets come with a top accessory bar, bottom mounting plate to allow spacing them 5.5″ to 6.5″ apart. The included bottom plate (BPL-1098) is drilled to mate to a variety of mounts or mounting adapter plates – including the Tele Vue/Vixen Mount Adapter (AVT-1011) and Tele Vue Gibraltar-5 Head.

For NP127is or any telescope with outside tube diameter of exactly 5-inches.

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.

Our ring sets provide rigid mounting for astro-imaging with our 4" and 5" scopes. Bottom and top of each ring is drilled for ¼"-20 hardware, have bat-handle locks, and two Tele Vue accessory slots for ring-mounted accessories such as Starbeam with Tele Vue base, Sol-Searcher, Piggy-Cam and others.

Sets come with a top accessory bar, bottom mounting plate to allow spacing them 5.5" to 6.5" apart. The included bottom plate (BPL-1098) is drilled to mate to a variety of mounts or mounting adapter plates - including the Tele Vue/Vixen Mount Adapter (AVT-1011) and Tele Vue Gibraltar-5 Head.

For NP101/NP101is with outside tube diameter of exactly 4-inches.

Tele Vue Piggy-Cam

Secure your camera to Piggy-Cam for greatest flexibility in piggy-back photography. Piggy-Cam's 3/8" thick tilting base plate can be locked at virtually any angle allowing you the most pleasing photo composition.

The captive ¼"-20 lock screw rides in a slot making it easy to mount any 35mm camera. Though designed for Tele Vue telescopes, Piggy-cam's U-shaped mounting bracket is easily adaptable to most any scope

Concept: Piggy-Cam provides a solid, adjustable platform for piggy-backing your camera on a variety of telescopes. — Al Nagler

Tele Vue 2 - 1.25 Inch Adapter, HiHat

The "high-hat" adapter is specially designed with a high rise head to keep Tele Vue Barlows and Powermate™ amplifiers away from the diagonal mirror.

Tele Vue Imaging System Adapter - 2 Inch to 2.4 Inch

2.4" Adapter for 2" Accessories is another key component that expands the usability of your existing 2" accessories. The adapter allows any 2” accessory to connect to the Imaging System. This includes cameras and filter wheels with 2" nosepieces. This adapter includes dual thumb-screws and non-marring brass clamp ring.

The 2.4 inch imaging system connection is found on the Tele Vue NP-101is and Tele Vue NP-127is APO refractors.

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.

"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.

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: 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.

Tele Vue 0.8x Reducer Adapter to 2 Inch Focuser

This is a key component to the imaging system's versatility on non-"is" scopes. By placing the Imaging System Nosepiece for 2" Focuser in your standard 2" drawtube, you open up your telescope to accept the 2.4" Imaging System accessories and take advantage of the solid threaded connection.

Tele Vue Extension Tube 3.5 Inch

Telescope drawtube extensions help your telescope reach focus when not using a diagonal — as is the case in many imaging applications. They are also useful (with or without diagonal) when you need more out-travel for focusing on nearby terrestrial subjects.

Our extentions tubes slip into any telescope's 2" drawtube and include brass clamp rings to prevent marring of accessory barrels

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.

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 0.8x Reducer/Flattener RFL-4087

TV-102 and TV-102is

Model FL-4087 Tele Vue 0.8x Reducer/flattener TV102 is a 0.8x Reducer/Flattener for TV-102 and TV-102is scopes and any 800-1000mm focal length refractor for imaging with up to 35mm camera formats. For TV-102 (non-"is") it requires the RAD-1074 Reducer Body Adapter for 2" focusers.

This reducer/flattener requires Imaging System camera adapter such as CWT-2070 (Canon Wide T-Adapter with Bayonet for 2.4" Focusers), STL-1071 (SBIG STL Camera Adapter), or TRG-1072 (Standard T-Ring Adapter) to connect to camera.

Looking for a corrector for the Tele Vue 101is/127is? Check out the Tele Vue Large Field Corrector.

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

To maintain a flat, rigid base for heavy camera packages, Gemini's shell consists of two parallel plates machined from MIC-6 tool plate providing flatness within 0.001" (25 microns). Seven precise stand-off spacers maintain the 2.25" separation of these plates. The rotating drawtube is moved linearly with 1/2" of total travel using a premium timing belt driven by a high torque stepper motor. The entire package is accented with a beautiful carbon fiber wrap. Dual RJ45 connectors provide connection to the Gemini Control hub. The independent rotating drawtube is supported by a custom X-cage bearing system supported by large, 6mm chrome ball bearings.

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.

Multiple Options Available:

Each Gemini package comes complete with everything needed to connect. An optional Hand Control allows manual access while at the telescope. WiFi add-on board mounting plate, precision external temperature probe, and motor-specific cables round out a complete integrated package.

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.

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.

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.
