SVBONY SV133 2″ Manual 5-Position Filter Wheel

Product Overview

The SVBONY SV133 2″ is a manual filter wheel with five positions for 2″ filters. It lets you switch filters with a camera attached or a 2″ eyepiece in place, so a session is not interrupted by unthreading filters. SVBONY lists it for 2″ eyepieces and for DSLR and CCD cameras, and builds it for frequent, long-term use.
