The Perfect Guidescope ☺
Thursday, 10 May 2018  | 

The day I received this amazing bit of kit, I was out that evening testing this with a Loadstar x2 camera and WOW!!! pinpoint stars across the whole FOV. I have used many finders over the years and this one is quality and very easy to use, plus no guide camera cable getting twisted when focusing ☺☺☺

This finder has the looks, but the build quality and performance are where this finder shines.

Taking it out of the box it feels like a miniature telescope instead of a finder. It is beautifully made and the focuser is smooth. Connecting a guide camera is simple and feels secure. I have used it on 20 minute exposures with no issues.

There are cheaper options out there but nothing comes close to the quality of this finder. I just wish they had included a diagonal.

This is just what I have been looking for - longer FL than a converted finderscope but shorter than an ST80. Better focuser than both the aforementioned and much nicer glass ! The qulaity doesnt disappoint - very nicely made, very smooth and well engineered focuser and well made rings and dovetail. As a trial I focused on a rock about a mile away and defocused in and out and the rock stayed bang in the middle of the fov. The focuser has a T2 male thread on the aft end so I fitted a T2 to C mount adapter to screw my camera on to to create a slop free system. It works superbly. Negative points = none at all.

Your Question:

Q1. Will it achieve focus with a 1.25" prism diagonal (for example, the cheap Celestron one)?

No. Unfortunately not.
The Sky-Watcher EvoGuide 50ED will not work with a star-diagonal so is not suitable for use as a compact rich-field telescope.
