The Explore Scientific G-11 Upgrade Kit allows the owner of a Losmandy G-11 to upgrade to the ExploreScientific/Losmandy G-11 with PMC-Eight GoTo System, thus allowing the G-11 to be controlled by any ASCOM-compatible software. This upgrade can be applied to any Losmandy G-11, be it an older or current model regardless of whether it has the Gemini system - - INCLUDING non-tracking, non-motorized versions. The upgrade is performed by Explore Scientific technicians at Explore Scientific’s headquarters in Arkansas and results in a fully-functional and thoroughly-tested Explore Scientific/Losmandy G-11 with PMC-Eight GoTo System. To learn more about the features of the upgraded G-11 see the product description of the Explore Scientific/Losmandy G-11 with PMC-Eight GoTo System.
