Product Description
Specially designed for the FRA400C, this 0.7x reducer adopts a triplet lens design, it can reduce the overall focal length to 280mm and the focal ratio to F/3.9 while providing a flat-field correction. When used with the reducer, the FRA400C supports full-frame imaging and the back focus is a standard 55mm.
The shorter focal ratio 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-inch filter thread for convenient filter attachment.
