Looking for a very useful pair of giant binoculars? These will do! They’re not the prettiest I’ve seen – painted red, with paint chips here and there, tan underneath, so possibly used in North Africa – but they’re in good working order.
If you’re not familiar with these, you can see a review on Cloudy Nights. These are the Busch-designed D.F. 10x80 binoculars – DF standing for Doppelfernrohr, or Double Telescope. They have a 131m field of view at 1000m; 280mm focal length for a 3.5 focal ratio; 70-degree, 5-element Erfle eyepieces with individual focusing; 45-degree Schmidt roof prisms; and intraocular adjustment.
This particular pair was made by Schneider in Bad Kreuznach, as shown by the dkl impression above the serial number. I’ve read that the triangle signifies “improved lubrication,” but I haven’t found any ideas about what the X might mean. The serial number is 74754.
These have four filters that can be dropped into the optical pathway using the dial above the left EP – Klar (“clear”), Dunkel (“dark”), Mittel (“middle”), and Hell (“light” – go figure!). The Klar filter drops into place cleanly, but the others don’t always fall exactly into place. Still, for astro use, I’ve only ever used the Klar!
These appear to be uncoated, which according to some reviewers is a good thing, given the questionable quality of the coatings they used on some of these. The right lens (that is, for the right eye) is totally clear as near as I can tell; the left lens has what looks like a water stain about 2cm x 2cm against the rim, as well as three pinpoint spots inside the lens. I’ve tried to show the stain in one of the pictures. These do not appear to affect the viewing. I have not tried to take these apart to clean them at all.
These have given me the most remarkable views of the moon, the Pleiades, etc. I don’t really have a suitable mount for them, and I need to downsize my astro gear, so I’d like these to go to a good home. (They have a screw hole for a standard tripod mount on the bottom, and I’ve been using them with my carbon fiber camera tripod, if you can imagine that – eh, it’s worked!).
I’d like $450 shipped CONUS, and I think that’s pretty fair, but I’m always open to offers.
