The SharpStar field flattener & reducer for the 140PH is a 3" dedicated corrector with a reducing power of 0.74x. It reduces the focal length of the 140PH to 673mm and the focal ratio to f/4.8.

This 3 element corrector delivers a fully illuminated and corrected field of 44mm, making the telescope compatible with full frame sensors. The working distance between the flattener and the sensor is 55mm.

The SharpStar flattener can be connected to the focuser of the Sharpstar 140PH by using the M88x1 male thread, and on the camera side there is the universal M48x1 male thread. The reducer can be rotated 360 degrees.
