Sky-Watcher 0.85x Reducer/Flattener for Evostar 72ED

The Sky-Watcher 0.85x reducer/flattener is designed for astrophotography with the classic Evostar 72ED. It reduces the effective focal length by a factor of 0.85 and improves field correction towards the image corners.

A camera-side M48 adapter ring is required, matched to your camera mount, for example this Canon M48 camera adapter. This reducer is specific to the Evostar 72ED; check telescope compatibility and camera spacing before ordering.

If you use a different Evostar tube, see the 0.85x version for the Evostar 100ED or the version for the Evostar 120ED. These models are telescope-specific and not automatically interchangeable.
