Question Can someone please teach me how to use an EQ mount properly?

Hey guys and girls,

I have a German-type EQ mount. I've balanced the scope in the declination and right ascension axes through setting the counterweight position appropriately. I understand that the right-ascension axis has to be set to my latitude.

What I don't understand are the dials (marked 0-23 on the RA axis and every 10 degrees on the DE axis) on both axes. Especially the fact that the RA axis dial can be moved around...

So the idea is...
  • Set up mount and scope.
  • Aim RA axis to south pole (not magnetic south).
  • Set RA axis to latitude.
  • Then ???

I understand that objects can be pinpointed by RA/DE - but I also don't understand in stellarium what the different references are... you have
  • RA/DE (J2000)
  • RA/DE (of date)
  • Hour angle/DE

I know this is an ultra-noob topic - but I searched and couldn't find anything comprehensive as a thread...

If someone can please guide me through the rest of the steps and how to use the EQ mount appropriately, that'd be great!
