IRotatorV2..::..Position

Remarks

The position is expressed as an angle from 0 up to but not including 360 degrees, counter-clockwise against the sky. This is the standard definition of Position Angle. However, the rotator does not need to (and in general will not) report the true Equatorial Position Angle, as the attached imager may not be precisely aligned with the rotator's indexing. It is up to the client to determine any offset between mechanical rotator position angle and the true Equatorial Position Angle of the imager, and compensate for any difference.

The optional Reverse property is provided in order to manage rotators being used on optics with odd or even number of reflections. With the Reverse switch in the correct position for the optics, the reported position angle must be counter-clockwise against the sky.
