Schott Suprax blanks ready for polishing
Here are the two blanks Schott Suprax 8488 ready for polishing. They are 456 mm in diameter (to have a useful diameter of 450 mm) and 50 mm thick. They will be processed with parabolic shape at f/3. These mirrors are made for the first two prototypes of TI 45 Astrographs.
Will you have any ti45 scopes to see at the New Mexico office? I travel through there and would be interested to see.
Thanks,
Robert
