This is a low profile, 2" threaded visual adapter for use with the 3" Stellarvue focuser. This 2" adapter accommodates 2" accessories using a compression ring clamp. Please note, this is for the 3" Stellarvue focuser found on the SV080T-3SV and the standard 3" focusers on the Stellarvue 102T refractors. It will also work on the former SVQ100 astrographs that used a Stellarvue 3" focuser (not the Feather Touch).
