I have for sale a pair of the finest center focus porro-prism Astro Binoculars ever made - the Carton Alderblick 7x50's.
These are in MINT condition except for one small indent to the covering on one lower objective tube. Optics are flawless and have beautiful purple multi-coatings.
These have a 1/4" x 20 socket for a tripod adapter with the cap in place. Of course, being 7x50's, a tripod is not really necessary. Right eyepiece is adjustable for differing diopters.
Included in the package: the binoculars, two objective covers, one-piece "rainguard" eyepiece cover, strap, and case. Everything is nearly like new.
$200 shipped insured USPS Priority Mail in the USA. Paypal or certified funds.
Thanks for looking and keep looking up!
