SVBONYSV165 Mini Guide Scope 30mm F4 Finder for SV305 Pro Compatible with ZWO QHY Orion Auto Guiding Cameras

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.)

Lo uso como tubo guia y me da muy buen resultado. No agrega mucho peso a tu montura y te permite hacer exposiciones mucho mas largas.

Good quality used for guide scope and it did what it was supposed to do.

Svbony guide scopes are budget choices that do the job

Really easy to focus, and works really well. For the price, it is a great buy. I have attached an image I took using it (as a guider)

Excelente material 👍🏻

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

While compact and lightweight, the main issue I have with this guide scope is there isn't a way to adjust it to perfectly align with the telescope. As a result, whether you are using it visually or with a guide camera, what you see through this finder/guider may not match what you see through the telescope, thus rendering it relatively useless unless you are using a very wide FOV telescope.
