Yet another part of the collection I acquired.
**Selling these as a bundle only**
Vixen 9mm ortho in excellent condition. Tested on Jupiter tonight and gives sharp, contrasty views.
unbranded 6mm HM eyepiece
Moon filter (0.965" fitting)
Tele Vue 0.965" to 1.25" adapter
both eyepieces come with plastic cases
I've Googled 'HM' and apparently it stand for Huygenian Mittenzwey. According to one website "The Mittenzwey eyepiece is a small improvement on the Huyghenian, replacing the planoconvex field lens by a meniscus lens."
The HM 6mm is sharp only in the central 50% or so. It's more of a collector's item than something you're going to use regularly IMO.
Asking $50 or best offer for the bundle.
Enquiries by PM please.
