Beautiful, Big and Heavy (14kg). Its is built like a tank and is strong. A work or art both mechanical and optical.
When I photographed it for this ad, I saw the apparent fungus marks on the front element. They look worse in the pictures but are certainly there when I look. Internaly it looks clean. A few similar marks on the front element inside surface.
It looks like the fungus was cleaned. There are no wipe marks or scratches that I can see. But the anti reflective coating has been etched and you can see from the pictures.
I have put a temporary rack and pinion on the back. With a 20mm eyepiece (not included), there is a lovely view. But the HUGE secondary floats like a shadow in the field of view and is VERY noticeable. Not really usable like that.
I imagine its designed for camera use.
You can see in the picture that the back comes off by removing three thumb screws (2 are original with a bolt replacing the missing one).
Its gives lots of room to mount things on the back. Its really a great project for experimenting and playing with. A lens with a past and history.
Its $950. If your in Melbourne, I can meet you somewhere. It can be posted too, its 14kg.
Its really something to admire.

Rob,
Are you really saying this is a 1 metre telescope?
