Skywatcher Field Flattener for Evoguide 50ED

The new Sky-Watcher field flattener for the compact Evoguide 50ED mini telescope is designed up to APS-C format (28 mm diagonal). It allows high-quality astrophotography with the very compact and lightweight telescope. The field flattener is screwed on instead of the extension tube of the 50ED and allows the connection of a camera with T2 thread connector. In addition, it has a receptacle for 1.25" barrels with two locking screws on the camera side.

The flange focal distance is 17.5 mm and is therefore suitable for most guiding and astro cameras. Perfect also when travelling in combination with Sky-Watcher´s small travel mounts like Star Adventurer (Mini) or AZ-GTi!

The Sky-Watcher Flattener contains two multi-coated lenses and comes with two high-quality anodized aluminum caps as dust protection.
