The Kecks are counted as two telescopes because they operate separately. They are both counted in the oft-quoted count of 13 observatories on Mauna Kea, i.e., if you don't count both you don't come up with 13. Maybe you need to do a little more reading. That still leaves you with eight observatories that are hidden or unreported according to you. Where are they?
