About
A 0.8× reducer/flattener for Stellarvue's fast small refractors, correcting to about APS-C. Its distinguishing feature is a variable back-focus adjustment that can be dialled in to match a particular camera and telescope and then locked with a thumb screw — Stellarvue give starting settings of about 7.5 for an 80 mm f/6, 6 for the SVX090T and 9 for the 70 mm, each assuming an imaging train consuming 55 mm. It will also house a 2-inch mounted filter internally.
