I am looking to buy a zeiss spotting scope but I have noticed that they only go to 45x in the 65mm scope. Is there a screw in 60x power or is there only a 45x power available? I would rather get the zeiss but I may have to buy the Swarovski instead.

Nube,

With the Ziess Diascope 65mm spotting scope, you can only go with a 15-45x eyepiece.
