Ask a Question About This Product

Designed to work with the Sharpstar 140PH apochromatic triplet refractor, the Sharpstar 0.74x Reducer and Flattener produces a flat field and razor-sharp images across a full-frame image circle.

The three-element design takes the 140PH from f/6.5 to f/4.8. The camera end of the flattener has M48x0.75 threads, while the telescope side has M88x1 threads to connect directly to the 140PH focuser.

This flattener transforms the Sharpstar 140PH into a powerful and highly capable imaging tool.
