Hey Bill, I don't see a pier column going into your building. Is it hidden or not installed yet?
Nice looking obs, BTW.
Thank you for the compliment and your are right -- No pier: stability is achieved through the six underground pillars each 2 ft. wide and 4 to 5 ft. deep (over a ton of concrete). The floor is rock solid and I experience less than a half second shake after focusing. This affords me the ability to move scopes and mounts around as the need dictates.
Clear skies and of course, "Keep looking up."
