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.

For those who are interested in D & G refractors, here is their website:

I was tempted to buy one of their scopes too just out of curiosity, but put off by the fact they are only achromatic refractors (CA affects contrast & sharpness too) and the tubes are way too long. Are you sure the custom 15" costs USD$200k? Because the 12" objective only costs USD$8.5k and the 8" tube assembly is only $3700.
