AutoFlats can be opened via the toolbar or from the “Tools” menu by clicking on the “AutoFlats (capture flat frames)” menu item.  If it’s your first time opening AutoFlats, it will appear with no Flat Frame events, but don’t worry… adding them is simple.



Clicking the “Add Flat Event” button will add a new “Blank” Flat Event to the AutoFlats Run.  This is boring though (and barely useful). A better idea is to click the small dropdown arrow on the right side of the button, you will be presented with much more useful ways of adding Flat Events.



All of these options pertain to adding a new Flat Event in the context of specific light events.  Most are self explanatory, but brief descriptions of each follow.


  • Add flat events for active light events:  In the context of the current sequence, add a Flat Event for every “Light” event that is itself “active” (checked) and belongs to an “active” (checked) target.
  • Add flat events for active light events:  In the context of the current sequence, add a Flat Event for every “Light” event that exists (both active and inactive) and belongs to an “active” (checked) target.
  • Add flat events for active light events:  In the context of the current sequence, add a Flat Event for every “Light” event that exists.
  • Add flat events for active light events:  In the context of a “light” frame FITS file, add a compatible Flat Event.
  • Add flat events for specific targets: At the bottom of the menu, a list of targets belonging to the current sequence will appear. Clicking one will add flat events for “light” events that will / would be captured during this sequence (i.e. active light frames)
