A dedicated 0.8x reducer allows you to effectively shorten the focal length of the SharpStar 94 EDPH telescope to 414 mm. It has been designed as a quadruplet with one ED glass element, which, when connected to the telescope, generates a circle of full illumination with a diameter of 50 mm, ensuring a vignetting-free image even on full-frame sensors. In addition, it allows for very easy use of filters with a diameter of 2" while maintaining a 55-millimeter back focus.

• four-element focal reducer giving a circle of full illumination with a diameter of up to 55 millimeters, fully covering full-frame matrices
