Speed up your deep-sky imaging setup with the Askar 111F 0.74x Reducer, specially optimized for the Askar 111F flat-field refractor.
Reduces the Askar 111F focal length to 566mm and changes the focal ratio to a faster f/5.1, helping deliver wider views and shorter exposure times.
Perfect for capturing large nebulae, open star clusters, faint deep-sky targets, and fast-moving celestial objects with greater efficiency.
Built with integrated field-flattening correction to help reduce field curvature and keep stars sharp and clean from the center of the image to the edges.
Supports a 44mm full-frame image circle, making it a strong choice for full-frame astrophotography setups.
Features a triplet optical design for reliable correction and high-quality image performance when paired with the Askar 111F.
Provides a standard 55mm back focus from the base of the M48 male thread, making camera spacing straightforward for many imaging setups.
Both ends feature M68x1 threads, offering a stable and adaptable connection within the optical train.
Works conveniently with the Askar 111F photographic extension tube, which includes M54x0.75 and M48x0.75 adapters for direct connection.
Rear adapter ring includes a built-in M48x0.75 standard 2-inch filter thread, allowing direct installation of compatible astronomy filters.
Precision CNC-machined construction gives the reducer a durable, high-quality feel while maintaining accurate mechanical alignment.
Includes front and rear metal threaded caps to help protect the optics from dust when the reducer is not in use.
