SVBONY SV165 Guide Scope, 30mm Focal Ratio F4 Mini Finder and Guide Scope

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.

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.

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. 👏

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.

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.

It’s amazing the quality of the optics and overall build quality. I wasn’t expecting much having a limited budget to work with, but it easily exceeded my expectations. of course clouds and rain arrived with it so I haven’t had an opportunity to image with it yet, but after playing with it for a couple hours I have no doubt it’ll perform. thing is beyond rock soild and achieves plenty good enough focus for what it’ll be used for. I didn’t notice any meaningful aberration even on a 32mp sensor and detail was still better than most of multi-thousand dollar Canon L glass I’ve got… Been playing with astrophotograpry since film was the only option and this is the first guide scope I’ve owned, far better than looking down the scope all night with an off axis guider and reticle eyepiece and hand controller in the guide port… Technology has really spoiled us.

Very good quality very excellent optics

As advertised; works as expected.

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

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.

Como buscador (visual), se puede usar con un ocular de retícula iluminada, Para astrofotografía sirve muy bien para autoguiado

El buscador es de muy buena calidad y la imagen que da también lo es. Lo compré para hacer autoguiado en astro fotografía pero también sirve como telescopio pequeño y como buscador si tienen un ocular con mira o una cámara. Además es ligero y no agrega peso excesivo a la montura.

My wife bought me this scope for auto guiding and astro photography. the scope is great works well and provides a nice image with my ZWO camera. The scope is light weight and easy to use. it took a little time to spin the elements to the right focus but once focused it has been solid.
