Imaging time constraint in hours calc
Maybe options with slew to center checkbox
Think about moving some or all of the filtering to menus in the column headers
Norder download link, sort of:
  https://indilib.org/forum/general/11766-dss-offline-hips.html?start=0
See if I can just use UserRole or UserRole+1 for the non-display roles.
Altitude graph has some replicated code with the scheduler
Weird timezone stuff when setting kstars to a timezone that's not the system's timezone.
Add a catalog name, and display it?
