Sky-Watcher's EvoGuide 50ED is the ultimate new high quality 50mm doublet ED Guidescope, finder or ultra portable telescope, utilising premium world class Ohara S-FPL53 glass for the ED element. Corrections are amazing with the use of ED glass, colours are true and contrast is superb. With a focal length of 242mm it has a very fast focal ratio of just f/4.8. The telescope is equipped with a fine and precise helical focuser enabling sharp focus to be easily acheived visually or on your camera sensor.
For connecting your autoguider, cameras or eyepieces it has a T2 thread and 1.25" eyepiece holder. For exact collimation to the main telescope, collimation rings are provided, each with 3 non marring nylon tipped screws. The guidescope bracket comes with a SkyWatcher / Vixen style mini dovetail for standard finder shoes. The EvoGuide 50ED is a small, very high quality telescope which is perfect as a Guidescope, providing pinpoint sharp stars for easy and precise guiding.
Guidescope capability
The stunning optics and build quality allow this optic to perform as a compact yet very capable guidescope, with 1.25" or T thread connectivity. The bracket will allow direct fitment to many popular telescopes.
Premium Finder
ED optics mean better colour correction, with sharper stars and more contrast, the helical focuser means precise focusing and mechanical features such as metal thumbcrews with nylon tips result in accurate and reliable operation. Simply add any 1.25" reticle eyepiece to use as a finderscope.
Camera Lens
Take advantage of the FPL53 lens with it's superior performance, attach your DSLR with an optional T ring or use any 1.25" USB camera for superb high contrast widefield imaging.
Ultra Portable Telescope
It maybe only 50mm but with ED optics you can get stunning widefield views by adding a low power 1.25 " eyepiece in the precision helical focuser, a standard 25mm eyepiece will give around 10x magnification, easy to hold steady for handheld use.

Customer Reviews 
A beautifully crafted instrument, very well packed and delivered promptly. I’m looking forward to a clear night to try it out and expect good results. (21/11/2018) John Mason - Shrewsbury
Very good upgrade replacement finder/guide scope Frustrated by the difficulty of achieving good focus with the standard finder/guide scope supplied with an ED80DS-Pro I purchaed the EvoGuide. First impressions are very good with good control over focus and a clear improvement in guiding performance; used with a ZWO ASI120MM-S and PhD2. (16/02/2018) - Derby
