eg Sirius
[Position angle is taken as I've said from an imaginary line on the celestial sphere due North , increasing North to East in a clockwise direction - East following (will be on the right if you face North) -an example is in Sirius B being roughly around 90 degrees or more position angle theta East at this moment in time, and simply let Sirius b drift into the field of view if you let A go past your left West field stop so its glare is mitigated and its worth a crack every good night now!!
