Both of these 1.25" barlows are in excellent condition, with cap(s) and box.
$65 shipped for the Ultima, and $30 shipped for the Russell. The legendary Ultima barlow needs no comment. The Russell Shorty is a commercially made Chinese barlow of surprisingly high quality (not one of his also high quality homemade efforts) and with a full 27mm clear aperture (just as with the Ultima). I've carefully blackened the lens edges to enhance contrast on the Russell. Views through the Russell are quite close to the Ultima, but it requires a bit of focuser in-travel, so if your in travel is at a premium do not consider this one.
