Picked this up today. Seems to be complete and in really nice shape. I had to do some repairs to the case, that's about it.

 

Seems this is pre-1910?

I've read that Emil Busch's firm did the design of the optically extremely nice WWII 10x80 flak BT design, and that the Busch made units were slightly better than the other makers.

 

It ended up in East Germany and I think became part of CZJ.

 

A few EB scopes turned up with Google searches.

 

It could be a very nice performer. Let us know how it does. Good luck Zane.

Here you go. I am the current caretaker of a 68/790mm Busch refractor. It is of ca. 1920-1925 vintage and I love using it for quick peeks at planets, moon and the sun. I have high praises for the optics and mechanics. Sharp and contrasty views rivaling Telementor. Tripod beautifully made and sturdy.

My Busch 68/790mm. The attached "Erdansatz" allows for correct image orientation.

I'm missing that silver column thing so I had to shim the mount head into the tripod with some plastic. Do you think a piece of copper tubing would work as a proper replacement?

 

Also is there any way of determining the age? I was told by the seller that his great grandfather had gotten it before WWI.

My own Busch 68/790mm came with the chromed copper tubing but I guess any metal tubing may work just fine. From what I learned, Busch introduced Preisfernrohr in 1914. Focal length was 780mm then. A backwards positioned focuser like ours and a focal length of 790mm may indicate 1920's vintage. Also available was an improved 75/950mm A-Lens. Production of this great little scope ceased shortly before the outbreak of WW2. I love my Busch not least because I can set it up and start observing in no time.
