About this product

Model: optec_fastfocus_19711
Part Number: 19711

ptec's FastFocus Secondary Mirror Focusing System with FocusLynxController has proven itself to be a singularly unique solution to the limited back-focus of the Celestron EdgeHD telescopes. 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.

Multiple Ways to Connect

The FocusLynx Control Hub acts as the central controller to link the FastFocusto 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 aluminium 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.

Easy Installation with Fastar Compatibility

FastFocus is easily installed taking advantage of the removable secondary mirror of the Celestron Fastar. Installation and collimation is as simple as the popular Hyperstar f/2 imaging system.

For older older Celestron OTA's special retrofit kits are available to make them Fastar and FastFocus compatible. Contact Optec Sales for additional details.
