How the "Park" position works with the Schulman Telescope

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.

Schulman Telescope Implementation of Park

Different software programs handle Park in different ways:

Program Behavior
LCOGT GUIPark is a position only. Its state is asynchronous.
ACPPark will set park variable (recorded by ACP and LCOGT) to “parked”, send to the defined park position and turn off tracking
TheSkyConnects to telescope via “ASCOM Mount.” In this way, park is only a position. The behavior is like ACP if connected to a Bisque controller.

Fixing the problem

Below is the typical error encountered in ACP.

  1. First clear the error by closing the dialog window. If ACP closes, restart ACP.
  2. In ACP Park the telescope under the Telescope menu.
  3. Wait approximately 10 seconds for telescope to settle and return.
  4. In the Telescope menu select Unpark.
  5. Point the telescope to the next target as normal.

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.
