Focuser Control

Your Astro-Physics mount's control box has a focuser port that can be used to power a motorized focuser with a DC synchronous motor. A focuser connected in this manner can be controlled by the driver. The focuser can be moved manually by pressing the In or Out buttons, or from the ASCOM Focuser driver.

Here are descriptions of the settings:

Focus Speed: Fast or slow. Pick one and keep using it throughout a focusing session. There is no conversion value between Fast and Slow step movements.

Final Direction: This sets the final direction in the backlash compensation movements.

Backlash Comp. (mSec): This is the duration of the final backlash compensation movement in milliseconds.

Max Increment: Maximum number of steps in or out that can be moved. In this implementation a step is a specific duration in milliseconds of movement. A step count is multiplied by Step Multiplier to get the number of milliseconds movement that will be performed. For instance if Step Multiplier is 2 and the ASCOM driver asks the focuser to move 10 steps then the focuser will move for 2 x 10 = 20 msecs.

In: While pressed moves the focuser.

Out: While pressed moves the focuser in the opposite direction of In.

Reverse In/Out Direction: If checked reverses the direction that an ASCOM command and buttons will move the focuser.
