Explore Scientific Field Flattener for f/5 to f/7 Refractor Telescopes

This Explore Scientific 2" field flattener is designed to work with refracting telescopes with a focal ratio of f/5 to f/7. The flattener comes with fully multi-coated optics and 38 mm of clear aperture. Once installed on your 2" focuser, the field flattener does not cause any change to the telescope's focal length.

Included on the flattener body is a T-ring thread so you can attach a user-supplied T-ring to easily attach a DSLR camera or other compatible camera for astrophotography. In order to use the field flattener, 55 mm of back focus/spacing between the device and camera sensor is required.

The body of the Explore Scientific field flattener has a premium high glossy anodizing finish.
