  • 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.

  • I use it as an electronic finder
Size: 40mm
Bought the 40mm variant. Light weight like a finder. Good clear multi coated objective lens. Lots of focus (length) adjustability. The base fits in a standard Synta finder shoe and has three point adjustment so it can be aligned with the optical axis of the main scope. I use this little guide scope with an astro camera to plate solve to align my mount with the stars in the sky an electronic finder if you will. I like Svbony products. They are affordably priced, good build quality and durable performance. I would recommend. ... show more

  • Svbony SV165
Size: 30mm
This is a very good guide scope for the money. It is easy to get focused. I also own the 50mm guide scope made by Svbony and would recommend it to anyone looking for a good quality affordable guide scope.

  • Cheap and cheerful, it works like it should
Size: 40mm
The scope is decently made and lightweight. Easy to focus and the red locking ring actually works very well to maintain it. Not the most impressive optic but gets the job done. Paired with an old asi385mc and getting consistently good tracking. Worth the couple bucks spent.

  • Best starter guide scope
Size: 30mm
Works just as well as $200 guide scopes, and for only 50 bucks, it’s definitely worth it. I can get guiding under 1 arc-second. Focusing can be tricky, but once it’s dialed in it performs perfectly. (I did 3-D print a due shield for it but it’s not needed.)

  • great product

Works fantastic as a guide scope for my 5" SCT

  • 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. 👏 ... show more
