Sky-Watcher EVOGUIDE-50ED: Compact high-performance ED guide scope

Visit Sky-Watcher EVOGUIDE-50ED is a compact, high-end guide telescope specially designed for astrophotography, precision autoguiding and wide-field observations. Thanks to its ED objective using a glass element Ohara S-FPL53, It offers excellent chromatic correction and perfectly sharp, fine stars. With its 50 mm diameter, 242 mm focal length and fast focal ratio of f/4.8, This guide scope is ideal for long exposures requiring precise, reliable tracking.

The EVOGUIDE-50ED's optical system is based on an innovative ED doublet made up of two Ohara glass lenses, including an S-FPL53 lens renowned for its high optical performance. This combination effectively reduces chromatic aberrations and produces particularly high-contrast images. Stars remain punctual across the entire field, making the work of autoguiding software much easier and improving tracking accuracy during astrophotography sessions.

Thanks to its luminous aperture and compact design, the Sky-Watcher EVOGUIDE-50ED can be used in a variety of configurations. It excels as guide bezel associated with a self-guidance camera, but can also be used as a high-end researcher, Its small size and light weight make it easy to fit onto most equatorial mounts and optical tubes. Its small size and light weight make it easy to install on most equatorial mounts and optical tubes.

The bezel is equipped with a precision helical eyepiece holder compatible with 1.25” format accessories. This focusing system offers great fluidity and excellent precision, particularly useful for the fine adjustments required in astrophotography. The presence of a thread T2 also enables direct connection of many compatible astronomical cameras and stills cameras.

To ensure perfect alignment with the main tube, the EVOGUIDE-50ED is supplied with adjustable collimation rings equipped with three nylon-tipped screws. This system enables precise adjustment of the guide bezel's orientation for optimum tracking. Sky-Watcher also supplies a 45 mm dovetail bar, a thread 1/4”-20 compatible with photo tripods, as well as a mini finder mount for quick installation on a standard base.

The versatility of this guide scope makes it an excellent choice for both novice astrophotographers and experienced users looking for a compact, high-performance solution. Its top-quality ED optics guarantee very clean results, even with modern high-resolution sensors. It's also a practical solution for nomadic astronomers wishing to carry a lightweight, easy-to-transport instrument on the move.

With a recommended maximum practical magnification of 100x, The Sky-Watcher EVOGUIDE-50ED is primarily intended for wide-field imaging rather than high-magnification planetary observation. On the other hand, it offers magnificent views of the Milky Way, open clusters and large deep-sky objects when used with a suitable eyepiece. Its value for money and optical performance make it one of the best compact guide scopes on the market today.
