Movement Tab

This screen shows the current position of the focuser and provides the capability to command the focuser to a specific position or to nudge the focuser.


Current Position:

This section displays the current focuser position.

 

 

Moving Led:

Below the position is the Moving led which will light up red whenever the focuser is in motion.

 

Nudge Buttons:  You can nudge the focuser with the up button or the down button .  Pressing these buttons has the same effect as pressing the buttons on the hand controller to move the focuser.  The counts will initially move at a slower rate to allow small movements but will ramp up to the fastest rate within about 2 seconds.

Moving the Focuser to a Target Position:

The target position edit box can be used to command the focuser to a specific position.  Just enter the desired position into the edit box and then hit the button.

 

Reset the Current Focuser Position:  The focuser operates as an absolute position focuser but due to the wide range of motion found on some focusers the capability to reset the current position is provided.  Pressing the button will reset the focuser position to the value currently in the Target Position edit box described above.  This will not move the focuser.  It only changes the position shown on the focuser.  A dialog will popup asking the user to confirm the reset operation.  Normally you would focus your telescope and then use this feature to reset the current position to 5000.  This will insure that you will have full range of motion for performing autofocusing.  The focuser will remember it's position when powered down so if you do not move your focuser with the focuser powered down you should not need to reset the position every time.

Stored Positions:

The Stored Positions feature allow the user to save named preset focuser positions.  Hit the combo box arrow to display the list of positions you have saved.  Initially this list will be blank.  To store a new position you need to move the focuser to the position you wish to store, type a name for this position into the edit box, then hit the button.  The current focuser position will be saved into the registry with the name you provided.  If you select a name that already exists and hit the button then it will overwrite that named position with the current focuser position.  To use a stored position just select the desired position from the drop-down combo box.  The value associated with that stored position will be echoed into the Target Position edit box.  Then you just hit the button to command the focuser to that position.  You can remove a stored position by selecting the name for the position you want to remove and then hitting the button.

Halting Movement:  You can halt any movement of the focuser by pressing the button.  If temperature compensation is active when this button is selected the focuser will drop out of temperature compensation mode.
