Askar 0.7X Full Frame Reducer for FRA400C Refractor - FRA400C-RED Seestar Smart Telescope This is an iOptron 2"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
