I have used this as a guiding scope for my telescope for Deep Sky Objects Imaging and it has worked well so far for multiple objects. It is also relatively light and not too hard to install as well. The field of view is great for tracking the mentioned Deep Sky Objects. It also seems well built and I expect it to last for a long time as well.

Similar to other guide scopes but less expensive. It guides my mount with sub-arcsecond accuracy. The mount rings allow easy adjustment. Light weight and no flexure as scope changes position.

This guide scope works with my Zwo Asi120 mini camera, small main telescope and Zwo ASIAir. The autoguiding has accuracy between 0.5 to 2 arcseconds. This is mostly good enough for my main scope and camera that cover about 2.5 arcseconds per pixel. The main difficulty with this product is the initial setup of finding infinity focus. It took a very frustratingly long time to figure out how far to insert the camera into the tube, or how much to turn the focusing ring, to get any image. I had to search various websites to find pictures of other users' setups in order to estimate where the focus ring and camera should be. Once I got in range to see an object, it was easy to fine tune the focus for autoguiding.

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.

The 48mm tubes was the perfect solution for the long focus tube being out too far...

This 40mm guidescope is much better than the 30mm version which I also own. It can take extender rings to make it most convenient for backfocus using either eyepiece or guide camera. It is compact which is an asset. The feature I am most happy with is that the holder for the scope permits the aim point to be adjusted. The 30mm version has two large thumbscrews but they only hold the guidescope, it is not adjustable. The extra aperture and longer focal length are also nice. I much recommend the 40mm version over the 30mm version

SVBONY gear is quickly raising up the ranks in Astro/Optical Accessories.The Guide Scope is Branded by SVBONY but available under a variety of Brand Names World-Wide, sometimes at twice the price from companies that have a Bigger Brand name.The Scope works well and does a good job when tracking, especially when paired with ZWO cams.For the price, Highly recommended

Aunque he visto a usuarios realizar el seguimiento de un C8 con este tubo guÃa, lo cierto es que para mi montura tan solo es válido para focales inferiores a 300 mm. Este tubo guÃa es muy luminosos y con la ASI 120 mm realiza un buen seguimiento para focales bajas. no me funciona a 2000 de focal, lo cual es totalmente lógico. Repito, en mi experiencia, para focales cercanas a 300 mm es perfecto. muy recomendado para Red Cat 51, 61 o Radian Raptor o similares focales.
