Paul and Liz do all of their astronomy from their observatory located 4,000 feet up in the clean clear air of the Sierra NevadaMountains in southern Spain (inset).
The telescopes they use for imaging are a 14-inch Celestron C-14 Schmidt-Cassegrain (pictured) on a Takahashi NJP mount and a 4-inch Takahashi FSQ-106 refractor on an EM-200 mount for wide field imaging. They use SBIG ST8 and ST10 CCD cameras for their work and their images are regularly published.
They observe visually using a 16 inch truss-tube Newtonian reflector from SpaceWalk Telescopes of Georgetown, Texas and a mighty pair of Miyauchi 4-inch Fluorite binoculars.
