Sky-Watcher EvoGuide ED50 50/242 mm

EvoGuide 50ED — 50/242 guidescope

The EvoGuide 50ED is a compact 50 mm ED guide telescope with a 242 mm focal length and f/4.8 focal ratio. Its low-dispersion objective offers improved colour correction in a portable guidescope format.

Focus and camera use

Helical focusing provides fine adjustment for a guide camera. The original version is equipped with a finder bracket for attachment to a suitable telescope.

Mounting configuration

This original finder-bracket configuration is kept separate from the later dovetail-equipped version; the latter’s additional mounting hardware and assembled weight are not assigned to it.

Optional imaging correction

The dedicated EvoGuide 50ED field flattener is a separate accessory. Use its instructions for sensor spacing and camera attachment when configuring the guidescope for imaging.
