SVBONY SV165 Mini Guide Scope 30mm F4 Finder and Guide Scope for SV305C Pro, Compatible with Astronomy Telescope and ZWO QHY Orion Auto Guiding Cameras for Deep Sky Astrophotography

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.

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.

Very good quality very excellent optics

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.

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.

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. 👏

Works fantastic as a guide scope for my 5" SCT

Not appropriate for guiding with only 120mm focal length. Get a guide scope with over 200mm. 50mm or 60mm aperture guide scopes are much more appropriate.

Works as expected. An improvement over my old 30mm ZWO scope. Plenty good for focal lengths less than 700mm The scope is held by six rotating screws. It must be accurately aligned before use or your guiding will be terrible. This is normal. Just a warning for anyone new to this hobby.

Excelente calidad y precio, buen funcionamiento y tiempos de guiado excelente, recomendable

Item was in excellent Brand-new condition. And this guide cam is working like a charm. getting a guiding below 0.4 to 0.7 most of the time. Attaching the screen shot of Guiding graph from a Bortle 5-6 Sky from Haldwani, Uttarakhand.

Christmas present, recipient happy with the item. Does the job. Arrived well packaged and earlier than stated

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
