iOptron 8451 overview

  • 1Description

Eliminate vibrations and achieve finer and more precise focusing on your 6, 8, or 10" Photron Ritchey-Chrétien telescope with iOptron's Electric eFocuser. Once installed on the OTA, the unit plugs into the auxiliary port on compatible mounts for power, and allows it to be controlled using the Go2Nova computer hand controller running the current firmware version. A precise stepper motor with a synchronous drive belt delivers three speeds — low, medium, high — without vibration or noise. While the eFocuser is primarily designed for the iOptron Photron Ritchey-Chrétien series telescopes, it will also fit other RC scopes such as GSO, OPT's TPO, Astronomics' Astro-Tech, and Orion; it may work with other RC scopes that use the similar dual-speed focuser.

Using an electric focuser eliminates the need to touch knobs which cause vibration and allows a level of precision that hand-focusing is usually unable to achieve. The eFocuser also locks the position when the control button is released to eliminate backlash — a valuable function for astrophotography or when trying to resolve dim or close objects like binary stars or cluster
