Optec FastFocus System for Celestron C11 / Edge 1100

Price includes VAT, plus delivery

Optec's FastFocus Secondary Mirror Focusing System with FocusLynx Controller has proven itself to be a singularly unique solution to the limited back-focus of the Celestron EdgeHD telecopes. With the FastFocus system in place, any Fastar compatible Celestron OTA can function like many professional telescopes where only the secondary mirror moves to adjust the focus. The primary mirror and entire imaging train can be locked in place avoiding flexure and tilt at the image plane.

FastFocus is easily installed taking advantage of the removable secondary mirror of the Celestron Fastar system. The FastFocus system solves a number of problems for users of Celestrons larger SCT's. First, as already mentioned, it solves the problem of mirror flop with the Edge models as their Mirror locks cannot be used if primary mirror focusing is retained. Secondly the Edge telescopes have a back focus distance of 146mm in either standard or reduced configuration. If a focuser is placed on the back of the telescope all you can actually do is vary this back focus distance. While you will be able to change focus with a rear mounted focuser, you will also affect the corrected field. This is not an issue with secondary mirror focusing as this is done before the correcting elements in the Edge models. If using the C models, a focuser can be fitted to the rear of the scope and a corrector after that. However there is limited back focus available and use of a corrector like the excellent ASA SCT reducer is not possible as it needs to be placed directly on the telescope. The Optec FastFocus system solves all these problems.

The FocusLynx Control Hub acts as the central controller to link the FastFocus 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 1 and an optional Focuser 2 port are available at the top of the FocusLynx hub with 12VDC Power, Network, optional Hand Control, and Serial connection ports available at the bottom. An optional aluminum mounting plate makes it easy to mount the FocusLynx Hub to any telescope pier or mount.

Using the ASCOM Local Server model, Optec's FocusLynx Commander software allows multiple clients to connect simultaneously to the FocusLynx hub. Additionally, embedded webservers in the wired Ethernet and WiFi connections enable FocusLynx to generate a control interface accessible through any web browser or smartphone. Free Android and iPhone applications search the local network and load the interactive webpages. Because these pages are generated by the hub itself, once you are connected, there is no further configuration required: just connect to your focusers and enjoy remote wireless focus control with the optional 802.11 WiFi add-on.

Any ASCOM client, Mac users of TheSky X or Equinox, or any web browser can be used to control the FastFocus focuser attached to the FocusLynx hub. With the optional FocusLynx WiFi module installed, the FastFocus can be controlled through any iPhone or Android device.
