I have an excellent condition Leica zoom (7.3-22mm) eyepiece and Leica factory 1&1/4" adapter for telescopes for sale. Action on the zoom and extendable eye cup is very smooth. This is a great zoom (check out the Cloudy Nights review). Asking $275 plus shipping. Will consider partial trade for 16 - 20 mm TV or other plossls with eyecups or 5-6mm Lanthanum.
