This is the recommended method of setting up alignment for planetarium programs with a SYNC function
With “Append on Sync” selected, any stars that you sync using your planetarium program will be added to the N-Point alignment data. The pointing model is “fine tuned” based upon the additional points added. This is unlike the dialog based alignment where the model is simply shifted to match the new point.
Essentially the steps are:
If less than 3 points are added, the driver will operate in the “Nearest Point” mode. As soon as 3 (or more points) are added to the pointing model, the driver operates in the “3‑point + Nearest Point” mode. You can choose to use “Nearest Point” for all slews by selecting this option in the “Alignment Behavior” drop down. Generally speaking, your best choice is to use the “3‑point + Nearest Point” option that lets the driver switch to “Nearest Point” only when necessary.
Special Instructions for Stellarium:
In order to accomplish a SYNC with Stellarium use the <Ctrl 1> keystroke to activate the Stellariumscope window (old Stellariumscope) and select the appropriate button.
With the more recent Stellariumscope use the <Ctrl 2> keystroke or the keystroke that you have defined for SYNC.
