This is a rather nice, new 6 x 30 mm right angle finder for people who -- like me -- are getting too old to get down on their knees to squint upward at the zenith. Unlike some similar looking items being sold these days, however, this one has a pretty good Kellner eyepiece (and a better quality, replacement objective) and thus offers a decent field of view for locating objects in the sky. Honestly, this really is a nice finder, if you are looking for something like this.
Asking $25.00, including postage w/in the USA for the finder. If you need a quality mounting bracket, I still have a NOS Celestion/Vixen single stalk type, with detachable base, that I'll throw in for an additional $12.00, still including all the postage w/in the USA.
