The glass telescope inside the Grosser Refraktor on Telegrafen Berg in Potsdam. 11.2 m focal length and a diameter of 80 cm for the lenses. In parallel to the telescope is a smaller one mounted, with only 50 cm diameter lenses used for is searching as a kind of sighting telescope. The telescope started operation in 1899, tracking of the stars was done purely by mechanics, a clock work.
It was rainy and my camera adapter didn't fit, so no stars to be taken.

What a brillian pair of shots' Detlef. Love the hints of flare by the eyepiece, it adds a touch of drama. I also like the view of the observatory very much, especially with the figure, observing you, observing it.

You know, I have never been there - I must rectify that!

Good shots, and perfect in black and white.

Very good indeed, especially the last one.

Thanks all.

Yes Pete you have to. The science park can be visited, there is normally no entrance restriction as passing the security at the gate. I could took the second shot from the top of the adjacent Michelson House. That gave a better perspective as standing directly in front of the building. I was lucky, that the observer jumped in the scene.
