public enum class PierSideRemarks
Pier side is a GEM-specific term that has historically caused much confusion. As of Platform 6, the PierSide property is defined to refer to the telescope pointing state. Please see SideOfPier for more information on this topic.
Only used with telescope interface versions 2 and later.
ASCOM Library Implementation
Since we had the opportunity of a fresh start with the ASCOM Library, we decided to give the Library enum a name that better reflected its actual meaning: PointingState. The enums have equivalent members and meanings, with the Library's PointingState enum intended for use with Library components and the PierSide enum intended for use with Platform components.
