Guider camera control (P-200 only)

 

f9tvinit

Initialize the F/9 base guider camera. This command is very similar to f9tvhome.

f9tvhome

Move the F/9 base guider camera to the home position. This command is rarely used outside of the setup procedure, as it actually moves the camera head into the telescope beam, occulting part of the CCD field of view.

f9tvmove <offset>

Move the F/9 base guider camera by a specified offset. The final camera position is printed on the screen following the move. The units for the guider camera servos are very small, so offset will probably be a number on the order of 30,000. The range of movement is approximately 0 to 500,000.

f9tvstat

Print the present location of the F/9 base guider camera.

f9tvzero

Set the current location of the F/9 base guider camera to zero. This command is useful to mark the location where you determine the camera head is no longer occulting the CCD field of view.

p200f9

Initialize the software interface for the F/9 guider base. This command will probably never be needed, except possibly after you have logged out of the Microvax completely.
