Portable 32" pier for A-P 400 and 600 mounts. Can be adapted to other mounts. This very sturdy pier is ideal for astrophotography and is more stable than taller piers of this type. It disassembles into small package for travel. Additional post lengths can be purchased from A-P for other heights. It is in excellent condition. This pier currently sells for $470 from A-P.
