Vixen

A name that is also a standard

The name on the saddle

Across this site, “Vixen” appears far more often as a profile than as a maker. The narrow dovetail that most small and medium mounts accept carries the name, usually written Vixen/Synta, and a bar cut to it will not seat in a saddle cut for the wider Losmandy profile.

The products themselves

Three accessories: a counterweight published with its mass and bore, a 1.25 inch moon filter, and a polar scope for the Polarie tracker. Each is a precise part for a precise fitting.

One listing that contradicts itself

The counterweight gives two figures for its size that cannot both describe the same object. The page reports both and resolves neither.

Reading a Vixen page here

When a page elsewhere on this site says “Vixen saddle”, it is describing a width. When it says Vixen on this page, it is describing the maker.
