The JTW P75 is a direct friction drive mount that breaks the traditional rule that a heavy payload needs to break the bank. It's an engineered-for-purpose mount that is meant to be extremely economical, to do one job well and to do it reliably. This mount has a photographic payload of 75 kg!
The purpose of this mount is to open doors for astronomers and astrophotographers who require an observatory class mount without the significant investment that's usually required. This mount has very high performance and can also be upgraded significantly, it has an open source control system and can be maintained with COTS (commercial-off-the-shelf) components.
