- 400mm f/5.7 Achromatic Refractor
- Motorized Altazimuth Mount
- "GO-TO" Capacity
The 2.8" aperture and refractor design of this Discoverer make it great at yielding high-contrast views of the moon and planets. It also has a shorter focal length and faster focal ratio than the reflector Discoverer scopes, allowing for wide star field viewing. The scope arrives with two eyepieces, but accepts normal 1.25" astronomy eyepieces (offered by a host of brands) so you can have a fine selection of magnifications for any object of interest and seeing conditions combination.
This refractor is supplied with a 90° erect image star diagonal, which lets you observe "upright" images through the telescope at a 90° angle to the optical axis, which is particularly comfortable when viewing objects directly overhead.
