MW Tubus für LZOS 228 F/9

very rare example of a Zeiss 80mm f/6 Comet Finder, circa 1916. (Astro 30 cat. p.20). I have located only two others that have come up for public awareness in the last few years, one in Austria and another in Lazio, Italy. This brass instrument was designed as a wide-field scope to scan the heavens for comets. Therefore, it was created to operate at lower powers and not for high-powered detailed planetary work. It has a beautiful type "C" objective with a focal length of 49cm, serial #9088. The OTA minimum length is 25" and weighs a robust 25 pounds w/display pedestal. Awesome views of the moon and star fields! brief chain of ownership I have discovered for the Comet Finder. The previous caretaker was Walter Breyer who purchased the scope from Michael Sadigursky in California (1993). I can't find out anything about Mr Sadigursky, but I do know some info of interest about Mr Breyer. Mr Breyer was probably best known as the secretary of the Antique Telescope Society up until his passing. A little known fact about him is that he was a descendant of the founder of Breyer's ice cream which is very popular in USA. Included items: OTA w/objective cell 12cm balance/extension tube Triple eyepiece revolver for 2 - 0.965" oculars plus 40mm Kellner eyepiece Carl Zeiss 25mm Huyghens 0.965"eyepiece Eyepiece slide tube 0.965" Quick-release adapter (female) Quick-release adapters x2 (male) Aperture reducing cover Dew shield OTA clamp/trunions Mounting Fork for 20mm post Brass display pedestal w/20mm post (can be adapted to a tripod) Wooden display base No tripod included
