I have a brand new Zeiss microscope binocular head.
According to an article in Cloudynights :"Microscope Binoviewer's Advantage" the microscope heads can be adapted to telescopes.
Reference to adapting microscope heads can also be found in Microbehunter.com forum "Microscope Binohead & with mirrors" . The last paragraph refers to the model presented for sale here.
Price $120
Pick up Vermont South or can be posted.
Thanks
Zbyszek
