Kodak Aero-Ektar 7 inch (178mm) lens, F2.5. This is the famous lens used in high-altitude surveillance. Glass is mint: coated, clear, and unchipped. With a 3-inch aperture and F-stops to approx. F11, this makes a superb astrograph. Covers a 5x5 inch plate or film easily. S/N EM3014, made in USA. $95

4.25” mirror, long FL, coating in fair condition, no chips or scratches. $10

Intes 7x36 RA finder. Never used—incredible optics and built like a tank. With caps. $145

Finder rings, set up for 50 mm but could handle 35mm with longer screws. $15

Meade 87D lens/telescope. 1000mm F12.5, made in Japan. A catadioptric lens—not a Mak, looks like an SCT. Wide fast-focusing ring, tripod adapter, extension with Minolta t-ring. Other t-rings may be substituted. Also can be used as a scope, comes with .965 RA prism and 25mm MA eyepiece for 40x. In original box and packing, $125.

Finder ring, one piece for 6x30. Looks like the ones supplied with mounts like the Great Polaris. $10

Lens—very heavy, uncoated, looks like an eyepiece from a battleship scope or binocular. Diopter correction to +2 and –4. Three inches long, 2 inch field stop, 1.875 at the eyepiece. No markings, paint is rough, focusing is smooth but stiff. Glass is not chipped, but rear doublet has fog at the edges (separation) and front coating is 75% worn away. Sound attractive? How about $5 plus shipping; careful—this big boy weighs several pounds
