A ton of Makers sent this telescope in, it’s called the trackball telescope and it’s public domain, Jerry writes – “…I searched the U.S. Patent and Trademark Office database, and came up blank there, too. As near as I can tell, I have come up with a new design for a mount that not only eliminates the pointing problems of equatorial mounts and Dobsonian mounts, but also tracks. I call it the “trackball” because there’s no better name to describe it. Happily, another search of the USPTO database shows that the term “trackball” has fallen into the public domain, so apparently anyone is free to use it as a generic term for this type of telescope. Many people have urged me to patent the design, but I would much rather put it into the public domain so anybody can build (and sell) them as they wish…” Thanks Stella! – Link.
