He might be referring to the 500mm catadioptric fitted with a 2X TC since it would seem that his "luggage" as that small lens that we are all suspecting as a 2X TC (teleconverter).
If you put the TC on the 500mm that he has in the package, then it of course becomes a 1,000mm f:10..or f:16.
He is just trying to lure you into buying the package by using different big words to describe his stuff.
If however, you know what he has, then I would only be interested in the night vision given the price that he is asking for the lot.
