ASKAR 0.8x reducer for APO 160 telescope

ASKAR 0.8x Reducer for APO 160 APO Telescope

0.8x Reducer for Askar 160 APO - Larger field, faster exposures and superior optical quality

The 0.8x reducer for the Askar 160 APO telescope allows you to reduce the focal ratio down to f/5.6, significantly expanding the field of view and shortening exposure times. This makes it an ideal tool for deep sky astrophotography, especially for capturing extended nebulae, open star clusters and faint, fast-moving objects such as comets or diffuse galaxies.

This accessory not only acts as a reducer, but also offers field flattening, ensuring flat, sharp images throughout the frame, even when using full-format cameras.

Advanced optical design

The reducer incorporates a high-precision quadruplet optical design with full coverage of the 44 mm image circle, making it compatible with full-frame cameras. This ensures excellent performance even on the most demanding sensors.

Compatibility and connections

* Front thread: M92x1, for direct connection to the optical tube Askar 160 APO.

* Backfocus distance: 55 mm from M48 thread, standard for astrophotography.

* Rear threads included: M68x1, M54x0.75 and M48x0.75, facilitating connection to most astronomical cameras on the market.

* Integrated internal thread for 2" filters (M48x0.75), allowing filters to be mounted directly without the need for additional rings.

Robust and professional construction

The reducer body is CNC machined, ensuring excellent durability and mechanical precision. It is supplied with threaded metal caps at both ends, which protect the optical system from dust when not in use.
