- This is a rare Zeiss 110mm F15 OTA. It is about 100 years old and not many survived the war years. It has the "E" type lens which is the achromat version from that peroid. The tube itself is not original. It is an APM tube with a Vixen style plate for mounting onmodern type mounts. The lens cell and focuser are original. There is also a modern style extender and Zeiss mirror diagonal. This combination works on the focuser but there is only one position that locks down. Consequently, the diagonal angle can be positioned at any angle but only locked down at one angle. This is a slight Zeiss shortcomming that can easily be fixed by the next owner. Images are good but not fantastic due to the time period and glass types of the era. The tube is 54 inches long and weighs 29 lbs. I'm asking $2750 plus packing and shipping and insurance. Local pickup is preferred.
