Celestron 94155 Overview

  • 1Description

Eliminate vibrations and achieve finer and more precise focusing on your compatible Schmidt-Cassegrain telescope (SCT) or Rowe-Ackermann Schmidt Astrograph (RASA) with Celestron's Focus Motor. Once installed on the optical tube assembly (OTA), the unit plugs into the auxiliary port on your Celestron mount for power, allowing it to be controlled using its NexStar+ or StarSense computer hand controller running the current firmware version. If your mount isn't compatible with it, you can opt to control the focus motor from a laptop with the addition of an optional USB cable or 12 VDC power adapter.

Helpful for visual observation and indispensable for astrophotography, a precise DC servo motor delivers three speeds—low 8°/sec, medium 32°/sec, high 128°/sec—without vibration or noise. 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.

You can use many types of astronomy telescope control software that have focuser control by using the Celestron Unified ASCOM mount driver that is available as a free download. Celestron also offers a free download for Windows that will enable direct control of the focus motor without the need for an ASCOM driver.
