On a general telescope park positions can be defined by a physical limit switch/indicator or through software by means of defining a particular telescope position. Some software programs also couple the position of “Park” with the action of moving to a park position and then turning off sidereal tracking. Not all software programs do this.
Different software programs handle Park in different ways:
Program | Behavior |
---|---|
LCOGT GUI | Park is a position only. Its state is asynchronous. |
ACP | Park will set park variable (recorded by ACP and LCOGT) to “parked”, send to the defined park position and turn off tracking |
TheSky | Connects to telescope via “ASCOM Mount.” In this way, park is only a position. The behavior is like ACP if connected to a Bisque controller. |
Below is the typical error encountered in ACP.
In step #2, even if the telescope is already physically at the Park position, re-parking will synchronize the variable states of Park in the LCOGT GUI and ACP. Simply selecting unpark will not work.
