Optec TCF Lynx 2 with Optec 2400DM Adapter

Optec TCF - Lynx 3" and 2" focuser

TCF-Lynx Temperature Compensating Focuser

A small change in ambient temperature can cause otherwise sharp stellar images to bloat in size, ruining the final image and wasting precious observing time. That solution is a temperature probe built into the TCF series focusers- and this is a combination of Optec's time tested and proven TCF focuser with the FocusLynx Controller Hub.

Mechanically, the Optec TCF - Lynx focuser is a robust Crayford style motorized focuser with high repeatability, no play and nearly zero backlash. Optec's implementation is ideal for applications which require exact focus such as CCD imaging or film astrophotography.

Optec FocusLynx Controller

The Optec FocusLynx Controller Hub is necessary for operating and is included. More information are available here.

With the FocusLynx Controller hub you can link the focuser to the same control hub that functions with any FocusLynx product- allowing you to more deeply integrate this with the rest of your setup! The integration of the FocusLynx with the TCF focuser expands the compatibility of its serial protocols from PC to also include USB, Ethernet, and Wireless WiFi capability- a noticeable upgrade in the ease of usability for the setup as a whole, as it allows you to have a much easier time linking this top quality focusing device to your PC or Laptop to control it remotely.

The Temperature Probe in the motorized TFC Focuser is a useful device- and now you can have it hooked up to the FocusLynx Controller- giving it the orders it needs to put that information to use, compensating for temperature changes based on the data that probe gathers, and shifting about the entire focuser based on guidance from the FocusLynx controller. This includes a 7-ft. Cat-5e cable for FocusLynx to TCF-Lynx connection- creating the link that enables you to utilize the FocusLynx's expanded compatability and finer level control with the TCF's high quality mechanics and temperature probe!

The TCF focusing units have a geared stepper motor that rotates the drive shaft with one step rotation of the motor equal to a 0.000086 inch movement of the drawtube. The resolution is 0.0022mm (2.2 micron) per step for the 2" TCF Focuser and 0.0025mm (2.5 micron) for the 3" TCF Focuser.

For a non-software controlled focusing the Optec hand controller is required (# 1317510)
