I think this is a simple question but just want to make sure I understand it correctly.

 

In Andy Galasso's best practices for PHD2 he states with regards to calibration:

 

Within +/- 10 degrees of Celestial Equator (Dec = 0)

Within an hour of Celestial Meridian

 

In the attached image I circled a location in Stellarium as to where I "think" I should be picking a guide star for calibration. Is this correct?

Here's a cheat code:

 

In PHD2, go to Tools > Drift Align.  It'll show your current meridian and equator offsets.  Set 'Slew to' to zero in both boxes, hit 'Slew.'  That'll point you directly at the intersection of the meridian and equator (subject to pointing accuracy) no matter what time it is.  If you can't find a star there, nudge it around a little til you find one.
