  • On the atioff projection map, how to draw a circle (e.g. telescope field of view)? suppose, telescope pointed at (Ra0,Dec0), FOV is a circle with radius R0
  1. Change the coordinate system from celestial to the designed coordinate (pole at Ra0,Dec0).#Then the circle in the new coordinate system is simply DecP=90-R0#change the new coordinate system back to celestial
