Sky-Watcher - Evostar 150DX Reducer/Flattener (.77x)
The Sky-Watcher is a dual-purpose flattener and reducer designed for use with their EvoStar 150DX refractor optical tube.
It features a 0.77x focal reduction and a field flattener, which corrects the spherical distortion caused by curved lenses.
As a focal reducer, it helps you reduce the scope's focal ratio and create wider fields of view.
This allows you to take more pictures with less exposure time.
The Sky-Watcher reduces the f/ratio of the optical tube to f/6.2 from the standard f/8.
It also reduces exposure time by 66%, allowing you to take more pictures with less time.
Its built-in back focus ring and M48 ring allow you to use different filters to create better images.
It mounts filters such as light pollution, moon, and polarizing.
It features a 34mm flat field that reduces the spherical aberrations in the field of view and produces clear images without the appearance of streaking or curvature.
It's compatible with both full-frame and APS-C cameras.
Limited 2-Year Manufacturer Warranty
