• The Askar 0.75x reducer brings the Askar 60F’s focal ratio down to f/5.1, providing a faster optical system and built-in field flattening.
• The reduced focal ratio delivers a wider field of view and allows for shorter exposure times, improving deep-sky imaging performance.
• Features a triplet optical design with a 44mm image circle that supports full-frame sensors, making it well-suited for deep-sky astrophotography.
• Provides a standard 55mm backfocus from the M48 thread, matching common industry configurations.
• Both ends of the reducer use M50×1 threads for secure connection.
• When used with the photographic extension tube, M54×0.75 and M48×0.75 adapters allow direct attachment; the M48×0.75 adapter also supports direct filter installation.
• CNC-machined construction ensures durability, and front/rear metal caps protect the reducer from dust during storage.

The Askar 0.75x reducer adjusts the Askar 60F's focal ratio to f/5.1, simultaneously offering field flattening as well as a faster optical system for better deep sky observation with wider field, a major plus for shorter exposure times if needed.

Implementing a triplet optical design and having a 44mm image circle which supports full frame, coupled with the Askar 60F it serves as a great companion for deep sky imaging. The standard 55mm backfocus from the M48 thread is consistent with industry standards and both ends are M50x1. When using the photographic extension tube, the adapters of M54x0.75 and M48x0.75 can attach the reducer ad in the case of the M48x0.75 can mount filters directly. The reducer is fully CNC-machined and comes with metal caps on both ends to keep dust out when stored.
