A Poncet Platform or Poncet mount is a type of equatorial platform (a telescope mount that adds an additional polar axis to non-equatorial mounts) that uses a simple polar pivot and an inclined plane. The motion of the mount allows any device sitting on that platform to track the apparent motion of the stars in the night sky (Diurnal motion). Its low profile and extremely simple design has made it a perfect complement to Dobsonian telescope style altazimuth mounted telescopes since it follows that designs philosophy of being easy to build using common materials, without the need for specialized tools or machined parts.
