Telescope/lens Astro Rubinar 10/1000

Astro Rubinar - TL 100 Special multilayer antireflection coatings at optical elements increase the light transmission; decrease the light dispersion; raise the contrast of a photo object. The photographic lens is furnished with a set of colour filters, and supplied in a handy carrying case. You can use whole system as astronomical telescope. Also you can use Rubinar 10/10000 as camera lens with any cameras using special adapter to M42 mount. Every other one I can find is missing parts. This one has all the original parts as shown - it takes two cases to hold them all. You can find just the lens for $200 average (which is a steal!) I’ll price the entire package firm at $300 I got all these specs somewhere on line, you might find more if you look around, but I think this describes it well. Description: Photographic catadioptric lens with multi-layer anti-reflection coating of the optical surfaces is designed as an interchangeable lens for reflex cameras with 24x36 mm frame size. The lens is used for black-and-white and colour photographs. The lens has a macro-limit, the nearest distance is 4 m. The using of the tripod makes it possible to arrange the frames by turning the lens with the camera into the special ring. The lens is designed for photohunting, close-up photography landscapes, architectural details, sporting contests and other remote objects. "CAUTION" these lenses may not work on all 35mm cameras with built in flash or other protruding devices on the front. The lens diameter at the mounting flange is 125mm or 62.5 mm radius. Measure your camera from the center of the lens mount to determine if any camera part extends more than 4 mm in front of the mounting ring within this radius. For example, the lens can not be used on the Canon EOS 10D camera unless you get the Teleconverter or some other Extension Tube.
