About this product

Model:  askar_f3.9_fra400_reducer

This Focal Reducer is designed for use with the Askar FRA400 Astrograph, the new Askar FRA400 f/3.9 full-frame focal reducer reduces the effective focal ratio by a factor of 0.7x, taking this already fast f/5.6 scope down to a f/3.9 system with 280mm focal length.

That means a wider field of view and a greatly reduced exposure time, making it easier to capture wide-field images of large deep-sky objects. The reducer has a back focus of 55mm and includes threads for M48X0.75 (2") filters.
