Description
Product Details

Designed exclusively for the Askar 60F, this 0.75x reducer reduces the focal ratio of the 60F to F5.1, offering a faster focal ratio while incorporating flat field correction capabilities. The faster focal ratio provides a wider field of view and shorter exposure times, making it particularly suitable for capturing large nebulae, dense star clusters, as well as faint or fast-moving celestial objects.

With a triplet optical lens design, this reducer supports a 44 mm full-format image circle. It has a standard focusing distance of 55 mm (measured from the M48 thread), with M50×1 threads at both ends for easy system integration. The included 60F photographic extension tube offers both M54×0.75 and M48×0.75 adapter specifications, allowing direct connection to the reducer for convenient setup. The reducer adapter features an integrated M48×0.75 thread for direct attachment of 2-inch filters, eliminating the need for additional adapters.

Constructed by CNC machining, the reducer features an excellent finish and comes with front and rear metal screw caps to protect it from dust during storage.
