Review: Does the job. - 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.
Review: I use it as an electronic finder - 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.

## Questions & Answers

**Q: What would be the ATO max focal length that you would use this guide scope with?**
A: I don’t know what “ATO” is, but I like to have my guide scope about half of the focal length and half of the objective size of my main scope. This “rule” has worked pretty good for me. So, this guide scope is 120mm focal length, which means you’ll be good at least up to 250 mm,( which is the size scope I use this guide scope with), and probably a little bigger. You also have to take into consideration your pixel scale, which is another lengthy subject all together.

**Q: I need to know the specification for the objective lens to the focal plane (true backfocus). The 45mm cited is is focus travel, not backfocus.**
A: Dear customer ,
Thanks for your contact.
the objective lens to the focal plane is about 26mm.

**Q: Why is the video showing an ota on a 20 dslr tripod?!?**
A: Dear customer ,
Thanks for your contact.
It could be connected to the SV503 telescope as a guide mirror.
In addition, SV165 could be directly connected to a UNC 1/4-20 tripod and used directly as a small telescope.
