Unlike some of the "toy" telescopes some people are commenting on and using as the basis of analysis, this is a custom designed and built 15"/F12 D&G refractor. It is worth well west of $US200K.
The eyepiece is a 31mm Nagler which gives 150X in that scope.

To give you some indication of the true size of this scope here is a photograph of it in its entirety, just prior to uncovering for the nights observing.
If you don't think it's all that big, consider that the ladder underneath it is a 6' mobile platform. The finderscope on the top is a 6"/F12 refractor. It also has a 5"/F10 refractor finder fitted to the far side which you can't see in this photograph.
Cheers,
