Wow only one piece of plastic thatís an achievement in its self, thatís the eyepiece cap ,every other part of this well made and very versatile bit of kit is metal except of course for the lenses which are of top quality all in all worth every penny .

Nice compact guide scope but...
Sunday, 24 January 2021  | 

I needed a small good quality guide-scope and this fitted the bill. However...
1) it didnít reach focus with my Lodestar guide camera., even with the supplied extender. I had to fit an additional T2 extension to get to focus.
2) the helical focuser is reasonably stiff but it doesnít lock down
3) there is a degree of rotary slop even if the focus wheel doesnít move. Not seen it affect guiding yet but I could imagine the image would shift if the guidescope cable took even the slightest knock during a session.

Amazing Little Scope
Friday, 22 January 2021  | 

So I bought this not with the intention of it being a guidescope, but to be a cheap APO refractor do to semi-widefield deep sky astrophotography. I was using a budget camera, with a small sensor, and paired with this short focal length, it was the perfect setup to just fit the moon in shot. I've got some really nice crystal clear photos of the moon, and there was no chromatic aberration at all on the moon, and the view of stars are lovely and sharp. With a sensor my size (7.99mm), the field is flat and all the stars perfect points, which is another benefit. The only disadvantage of using the scope as an imaging scope is that it can be hard to aim, as there is no guidescope, so you end up juggling the eyepiece (not included) and camera to get the object in shot. This is not a complaint however, as the scope wasn't really designed for this purpose. I've found that it works surprisingly well for deep sky astrophotography on a cheap EQ-1 Mount, and I'm currently upgrading it with stepper motors to make the tracking more accurate.
Due to it being quite cloudy recently I've only got a chance to test it briefly on the Pleiades, Orion's Nebula and the moon, but all have been a very significant improvement on the lens I had for my camera previously. The build quality is superb, and all the parts work perfectly, although it is a moderately heavy setup.
Overall, it produces lovely images and it is a great budget scope for those wanting an APO, However I cannot say anything about the field flatness with a larger sensor, as I have not been able to test this.

Puzzled
Friday, 11 December 2020  | 

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
Friday, 24 January 2020  | 

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.
Tuesday, 7 May 2019  | 

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.

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.
