## 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.

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.
