Vixen flip mirror system
I have a Vixen flip mirror finder to which I want to add a standard 2" filter. In actual fact, the thread on these is 48mm. The thread on the Vixen accessory is 49mm (WHY do Vixen always do things in a nonstandard way!?). The normal way around this (for cameras) would be to use a 48-49mm step ring, but some of these have more than 2" OD, so may not fit the focuser tube. Has anyone had any experience with this accessory?
