Askar 0.7X Full Frame Reducer for FRA400C Refractor - FRA400C-RED

This triplet reducer is specifically designed for the Askar FRA400C, and will reduce the overall focal length to 280mm and the focal ratio to f/3.9. Adding the reducer to the FRA400C will still allow full-frame imaging and the back focus is a standard 55mm.

The shorter focal ratio (from f/5.6 to f/3.9) enables the telescope to achieve a wider field of view and faster exposure times, making it ideal for capturing large nebulae, star clusters, as well as faint and fast-moving celestial objects.

The FRA400C reducer features an M48×0.75 rear-end adapter and has a built-in 2" filter thread for convenient filter attachment.

Note:  This reducer does not work with the FRA400 (non-C) refractor.
