Stellarvue 2" Visual Back-SVQ100 for 3" SV Focuser
This is a low profile 2" threaded visual adapter for use with any 3" Stellarvue focuser, including the 3" SV focuser used on the SVQ100 astrographs. This product includes the visual back designed for the Feather Touch focuser and has the adapter so it will thread into the Stellarvue focuser which has a slightly larger OD. This 2" adapter accomodates 2" accessories using a compression ring clamp. Basically, it allows you to use smaller 2" accessories with the larger 3" focuser.
