Sky-Watcher Evoguide 50ED Guidescope — 10199

The Sky-Watcher Evoguide 50ED Guidescope is a compact, premium-quality guiding telescope designed for astrophotographers who demand accuracy, stability and pinpoint star performance. Built around a high-grade 50mm ED doublet objective using Ohara S-FPL53 extra-low dispersion glass, it delivers outstanding sharpness and minimal chromatic aberration — perfect for precise autoguiding and wide-field visual use.

With a focal length of 242mm and a fast f/4.8 focal ratio, the Evoguide 50ED offers bright, crisp star images that make calibration and guiding faster and more reliable. The integrated fine helical focuser allows smooth, accurate focusing, even when using sensitive guide cameras.

Premium optical performance for accurate guiding

The ED doublet lens design controls colour fringing and produces tight, round stars across the field. This makes the Evoguide 50ED ideal for long-exposure deep-sky imaging, helping to keep stars sharp while your main telescope captures detail.

Flexible connection options

The Evoguide 50ED is designed to work seamlessly with a wide range of cameras and accessories. It includes:

• T2 (M42) thread for guide cameras and adapters

• 1.25" eyepiece socket for visual observing or reticle eyepieces

• Collimation rings with nylon-tipped screws for precise alignment with your main telescope

This flexibility means you can use it as a guidescope, finder, travel telescope or even as a compact camera lens with the right adapters.

Versatile mounting system

For maximum compatibility, the Evoguide 50ED now comes supplied with:

• 45mm dovetail bar for telescope mounts

• 1/4"-20 tripod thread for photography tripods

• Mini finderscope dovetail bracket for standard finder shoes

Wherever your setup takes you — home observatory, field tripod or travel rig — the Evoguide 50ED fits in easily.

More than just a guidescope

While designed primarily for guiding, the Evoguide 50ED is also excellent as:

• A wide-field finder

• A compact travel telescope

• A small, fast astro lens for night-scape work

Its lightweight build makes it easy to pack and carry, without compromising optical quality.
