  • Description

    Increase the efficiency of your SCT by upgrading to the Zhumell 11:1 Dual Speed Focuser for Schmidt-Cassegrain telescopes.

    High precision 11:1 dual focus

    The Zhumell SCT Focuser offers both coarse and fine focusing capabilities. Turn either one of the coarse focus knobs to make larger adjustments to your telescope’s focus, and then switch to the 11:1 fine focus knob to finish focusing.

    The term “11:1” means it would take eleven full turns of the fine focus knob to equal one turn of the course focus knob. This precision focus ability lets you make much smaller adjustments to focus than you could ever make with a standard focuser.

    Astrophotographers love dual speed focusers

    As you have probably noticed, the higher the magnification, the tougher it is to focus precisely. The Zhumell Dual Speed Focuser is a great upgrade for any Meade or Celestron Schmidt-Cassegrain Telescope, or SCT. Adding the ability to achieve fine focus will help immensely, especially when you are doing high magnification work, such as photographing the planets.

    Whether you are observing visually through an eyepiece, doing planetary or lunar photography with a simple tele-extender, or imaging deep-sky with a webcam or astronomy camera, you will love the Zhumell SCT Focuser. Upgrade your Meade or Celestron SCT today!
