About this product
Model: optec_LEO_19740_e130
Part Number: 19740-e130
Optec has developed this new, low profile, yet highly robust 3-inch focuser for telescope installations where back-focus is at a premium.
With the width of a typical 1-1/4" eyepiece, the TCF-Leo provides a unique focusing solution for the Celestron EdgeHD and other telescopes with limited flange-to-focus distances. The proven FocusLynx control system is included with every TCF-Leo and can be expanded to provide control for a second focuser. The FocusLynx system includes optional 802.11 WiFi and Hand Control accessories.
This package is a complete kit for replacing Takahashi's Epsilon-130 saddle plate and focuser. Requires some assembly on E-160 optical tube assembly.
Includes
-
Replacement saddle plate with Tip-Tilt adjustment for Takahashi Epsilon 160 Astrograph.
-
Leo Low-profile focuser with FocusLynx control hub
-
17833 - OPTEC-3000 3-inch to M60 x 0.75mm female thread. Fits Takahashi Epsilon-130 Field Flattener for TCF-Leo.
The unique shape of the TCF-Leo is designed to fit neatly between the lock and focus knobs of the Celestron EdgeHD C-11 telescope OTA. With a centre-to-edge distance of about 2.2-inches (55mm), the TCF-Leo works exceptionally well with Innovation Foresight's On-Axis Guider, providing clearance for large cameras and filter wheels above either of the flat edges of the TCF-Leo. Additionally, the TCF-Leo's 3600 receiver fits directly onto the 3-inch port of the Perseus Instrument Selector for the ultra-fine focus of a large format camera.
For owners of the EdgeHD Celestron C1400 telescopes, Optec offers a set of replacement knobs for the original lock knobs, which provide clearance for the TCF-Leo.
Nearly any telescope imaging system can be configured with standard Optec interfaces on both the telescope and camera sides. Specify any of our OPTEC-3600 telescope mounts or contact Precise Parts for a custom adapter to fit any telescope.
As a full 3-inch focuser, the TCF-Leo drawtube accepts any of our OPTEC-3000 adapters developed for the TCF-S3 and TCF-Lynx3 heavy-duty focusers. The optional Precision Centering Adapter allows any large 2-inch diagonal or eyepiece to be added behind the focuser. Visual users will appreciate the FocusLynx Hand Controller with a fine-focus rotary knob for no-touch operation of the telescope focus.
