For Sale: 24mm Brandon ep.
What's "unusual" about this eyepiece is that it has a nearly-new condition flat-top barrel from the '70s (stored for years in the back of a Vernonscope cabinet) but lens elements that were brand new a year ago (and still look that way). So it has the latest glass and coatings from Vernonscope with an older barrel design that doesn't keep a glasses-wearer from seeing the entire field. It's been used in a clamp-style diagonal so there are no set screw marks on the barrel.
This eyepiece gives very nice views- 50-ish degree field, dark sky, good contrast, pinpointy stars. I'm selling it because I don't find myself using this focal length very often and am saving for another project.
$150 includes shipping in CONUS.
