Review: Powerful focal reducer in a small form factor - make sure that's what you need - A powerful focal reducer in a small factor. I purchased it to help my guiding scope focus on large objects that took too much of my field of view and did not care about aberrations that might accompany this type of optics. Good value for the money.
Review: Still have to figure out focus distance- using with zwo120 and orion 60mm guide scope - I'm trying to find the focus point while using it with an Orion 60mm guidescope and a ZWO 120 camera & 1.25 adapter. I ordered an Orion 1.25" extension tube. Maybe that will help but I'm not sure. For $11 the lens looks OK to me. Hopefully I'll be able to use it. If not I will try it with my eye pieces.

## Questions & Answers

**Q: Can a filter be threaded onto this redeucer?**
A: This product has the same threading front and back as a 1.25" filter so it fits on the end of a 1.25" eyepiece.  However, I returned this product, as I discovered that placing the reducer at this point in the optical path reduced the FOV at the same time that it reduced the magnification.
