Framing Masks

 
The Framing Masks Panel is accessible from Tools tab
or with Alt+K shortcut.
 
Framing Masks Aid helps in framing object by same way during different nights or after a meridian flip. It is an alternative to PointCraft when there is no telescope/mount connection.
 
To create a new mask, select "Add New Mask" from the Mask list box, give a name of the mask. After that click with the left mouse button on few stars in the image that you can easily locate to put markers (second click in the same place removes the maker).
 
Later you can select the same mask from the list and to see the marker positions, then move the mount and rotate focuser till the reference stars match to the markers pattern. To see the new position you can enable the LiveView or to start a Frame/Focus imaging plan.
 
If the mask is created when the object was from the other side of the meridian, select the "Meridian Flip" option and APT will orient the markers in way that corresponds to the current object position. Don't be afraid that image will be rotated, your stacking program will handle this without any problems.
 
It is possible the create a mask using image from previous imaging session in order to frame the object by the same way. To do that use the image browser - Img Tab to load the image and mark the stars you want to use as markers.
 
To hide a mask, just close the aid.
