For the 1600 nothing beats an ATS for rigidity. I have found that wood tripods like the Berlebach will twist slightly with variable moisture in the atmosphere, and thus change the polar alignment. Not my choice for a permanent setup, but fine for portable use.
Our portable piers are also great for backyard setups and don't cost as much as the ATS.

Subject: [ap-gto] Tripod mounting of 1600GTO
I have been hoping to put my 1600GTO mount, due in February, on a pedestal in my side yard. This is looking like it may not be feasible, and I’m thinking again of the idea of tripod mounting. I have a Meade Giant Field Tripod for my 16” LX200 that I could have an adapter machined for, but that tripod may be too much to deal with easily.
I have a spare Berlebach Planet tripod rated for 120 kg, but I don’t know whether it’s adequate for the 100 kg of mount, scope, and counterweights that I have in mind (PlaneWave 14”, or failing that, a C14).
If the Planet is marginal for astroimaging with this setup, what’s a good option? Berlebach makes a bigger tripod, the Graviton, rated for 220 kg, but it’s 5x the cost of a Planet. The listing fo the A-P Eagle doesn’t mention a mount as big as the 1600. That leaves the Bisque Pyramid.
Any thoughts? Experiences?
