This scope feels solid and well-made and I was impressed with the image quality for the price. I tested it both for use as a guide scope with a camera (mono) and optically. The field is actually impressively flat with only minor distortions towards the field edge. However I do feel a little disappointed by the rigmarole required to focus the scope. I found that an awkward combination of three methods was required; moving the guide camera up and down the tube to get approximate focus, then a kind of shuffle of loosening the objective lens and then turning the focus wheel to 'take up the slack created' by this action. Maybe I was doing it wrong but this just seems overly fussy when they could just use an integrated helical focuser. C'mon ZWO, cheap as chips monoculars use a proper focus mechanism, would it really break the bank to employ one here?

Granted however most people will focus once and not have to touch focus again if the scope is only employed in one system doing one job, so I only dropped one star for this slight annoyance ! Other than that a lovely wee scope, well packed and delivered across the country within hours from FLO.

Was pleasantly surprised when this turned up. It's perfect for a compact wide-field rig and feels really good quality.
It hasn't had first light yet but I get the feeling it is going to be much easier to focus than my other guide-scopes as it has a focuser. Can't be beaten for the price in my opinion.

There are not many items in astrophotography that are cheap, effective and good to look at, but this is. Its well made, simple to use, works really well and for small focal length systems, I am not going to bother looking at anything else from now on. Even my old trusty ST80 has been put on the shelf. An ASI120 fitted straight on, it was easy to focus and holds focus well from the outings it has had, and because it is so small, it just makes guiding that much less of a hassle. Highly recommended and will buy another without worrying a jot for any other shortish FL system.

Guide scope works well with the ZWO ASI 120 mini camera. However, the thumbscrews supplied with the guide scope were far too big and don't fit into the holes provided. I had to borrow the correct 2mm screws from a friends Celestron just to try it out.

Tried this for the first time with a ZWO ASI290MM. Makes a perfect paring with the SpaceCat 51, (or RedCat 51) once camera installed and focus achieved, there's a locking right that holds focus, so between sessions there's no problems with focus getting lost. It's small light, and was easily able to pick up stars for guiding. It's a great piece of kit for any astro photographer.

Excellent little scope for guiding.
I use it with my Redcat 51 is a perfect match !

Not yet tried this small guidescope, but I am quite confident it will do a good job. What it has done for me, is lighten the load on my mount. Balance is now very easy to create, and that is so important. I'm sure my lodestar guide cam. will be a good partner for the little fellow, and I envisage no problems at all.

Fast and reliable. And quite cheap now (before Brexit). Highly recommended.

The ZWO Mini Guide Scope is well built and reasonably priced. I purchased one for use as a solar scope in a Raspberry Pi based project I'm currently designing. The small 30mm objective is fine for solar work, though at F4 focussing needs to be very precise and this can be quite difficult as the objective part of the scope is turned to achieve focus. The whole unit is made from metal, so it does feel sturdy. It would make a great little finderscope or lightweight guidescope.

Using this on my WO61 and the red it a great match for it. The scope is very nice quality and very compact, perfect with the ZWO120MM attached.
