As a 50mm telescope it is a lovely product, and more expensive than I needed as a guidescope. I spent a long time puzzling over it.

The first issue is that it looks as if you can just pop a mini camera into the eyepiece-sized hole at the rear and bring it to focus. I was planning to use the ASI290 MM mini. Not so. It looks as if the point of focus is set up for a camera that attaches via the T-ring adaptor - that is, the point of focus is slightly beyond the end of the scope. Luckily I have T-ring adaptors to play with and the addition of a 40mm (!!) extender brought it to focus with the ASI290 pushed fully into the eyepiece holder.

The second issue is that the helical focus ring moves freely. If there is a lock, I can't see it. The instructions do not mention a way to lock it. I had assumed I could bring the assembly to focus once and that would be it.

The third issue (less of an issue for me, I have an EQ6 mount) is that it is heavy, more so with a 40mm extender and camera. The weight is that of a small observing scope, not a guidescope. I think I will have to spend more money on a proper mounting solution.

Excellent guide scope
Tuesday, 29 September 2020  | 

I purchased the Evoguide 50ED guide scope to replace a four year old 60mm guide scope of very similar focal length for astrophotography with 980mm f/7 and 540mm f/5.4 refractor telescopes. I mostly use a QHY183M camera and filter wheel for LRGB and narrowband objects. I use an ASI 224c guide camera with a UV filter. The previous guide scope simply did nit provide adequate focus and guiding suffered using PHD2.

The Evoguide is very well made and the mini-Vixen bar solidly mounted. Mounting to the telescopes was easy and scope balance was easy. Mounting the guide camera required no additional adapters. Focus was great, with more guide stars are visible than with the 60mm guidescope because stars are significantly sharper all across the frame. Guiding improved with the three objects I have imaged so far (average 6 hours per object). Overall I am very pleased with this purchase and wish I had made the decision earlier. My only negative comment is that the helical focuser has a bit of backlash that I could not find an adjustment for. Once spot on, focus position locks well with a set screw and hasnít moved. FLO did a great job of promptly shipping and DHL did a great job of quickly delivering to the US. Thatís 5 star service!

Splendid guidescope

Well, there are rave reviews for this guide scope wherever you look, and I am not going to disagree.

Straight out of the box this is a quality piece of kit, it is extremely well made, properly engineered and aesthetically pleasing, more importantly it does the job.

I have used it in anger only one so far, but on the occasion the view on my laptop with clear, it quickly showed multiple options for guide stars, it didn't require any adjustment of the location on the telescope, (I have an X-Y adjuster which I do not think I will now use again, as this scope makes it redundant).

There are a number of reviews on various forums that suggest that this little scope can be used independently as a wide field viewing or imaging scope, even in the daytime, although I must say that I found it difficult to reach focus on either of those situations, even with a good quality diagonal.

On balance, this is a lovely addition to my equipment, and although expensive I think it was well worth the money.

I have had this scope only for a few weeks and havent had a chance to use it in anger yet, but from a little play in the garden with an old eyepiece Im very impressed and cant wait to put it to use as my new light weight guide scope.

EV Guide Scope 50mm.

This is an elegant and very practical little scope to facilitate
guiding your mount to capture data from your main Camera.
one big plus, is the low weight factor, which is very helpful when balancing one's imaging setup.
It can pick stars easily too, great objective despite it's 50mm. diameter.
the price in another plus factor too.

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 ☺☺☺

You won't be disappointed

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.


Please fill in the form below to ask a 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.
