Does the job.
Size: 30mm
Focus was easy. Decent quality for a guide scope. Light weight. Good price. If this is your first guide scope - you can’t go wrong here.

A nice small scope for Guiding
Size: 30mm
It is a nice lightweight scope for auto-guiding. My Orion StarShoot autoGuider Camera fits on it well. This scope accommodates enough focus thread length to focus perfectly on my sensor without elongating more than ~20mm. The red Focus lock ring also makes it easy to lock focus without losing focus and without any knobs or set screws to come undone. Once focused it shows stars very well without halos or anything like that so the guider camera can do its job well. It is much lighter and smaller than my Orion 50mm it will not be a burden to my Skywatcher mount. The ring mounts for this are great and the lock screws have plastic guides on the front to stop any scratches on the barrel when locking. The rings are a good fit and the base has 1/4-20 threads which is great! It seems to be a nice cheaper option to the ZWO guider scope. I am also pleased with how quickly it arrived, just a couple days.

Focuser is very basic but it works.
Size: 30mm
Fast shipping. Works well with my Asi174mm mini camera. The focuser is very badic and not smooth but wirks. For the price point good deal.

A telescope finder is essential, but it doesn’t have to be massive
Size: 30mm
This finder is meant for small telescopes used for astronomy photography. It’s compact enough that you don’t notice the weight, but provides plenty of field of view for find or tracking celestial objects. Can be used visually with an eyepiece or diagonal and eyepiece for viewing objects terrestrial or celestial objects. It is well built and made with quality metal parts that Will not break like plastic ones. It’s also not expensive for the use and build quality given the price. 👏

Tiny scope packs a big punch.
Size: 30mm
This guide scope has been a really great addition to my imaging setup. The optics are sharp, focus adjustment is smooth, and it paired pretty flawlessly with my sc715c as a guide camera… buuuuut I would love to get my hands on something smaller to pair it with like the sv905c, that way I can still use my sc715c as a planetary camera. Overall, guiding performance improved immediately and was more consistent tracking-wise during longer exposures. The compact, lightweight design is solidly built and easy to mount. Excellent performance for the price.
