Subject: Position Angle Scales Sent: Wednesday, March 24, 2010 11:58:47 From: Erwin Matys (firstname.lastname@example.org) We designed a position angle scale that can be printed on cardboard and placed between any 1.25-inch eyepiece and focuser. Once oriented, it points out the celestial directions in the field of view, shows the position angle and even tells the rotational directions of planets.
