Optec Lepus Focal Reducer

This factor effectively shrinks your telescope's focal length, which gives you a wider field of view and makes your system 'faster.' In practical terms, this allows you to capture more of the night sky in a single frame and reduces the exposure time needed to capture faint deep-sky objects.

The Lepus is designed to fit into any standard 2-inch focuser or eyepiece holder. However, it is specifically optimized for Meade ACF f/10 and f/8 Schmidt-Cassegrain telescopes, so you will see the best optical performance when paired with those specific models.

Yes, the unit uses an Optec-2100 dovetail interface on the camera side. You will need to purchase a separate camera-specific mount or adapter that is compatible with this interface to complete your imaging train.

To achieve optimal image quality and correction, you must maintain a back-focus distance of 105 mm measured from the flange of the focal reducer. Ensuring this distance is precise is critical for avoiding distorted stars at the edges of your images.

Yes, the unit includes M48x0.6 filter threading. This allows you to easily screw in standard 2-inch filters directly to the focal reducer, which is convenient for light pollution or narrowband imaging.
