I recently moved to southern Mexico (16 degrees N) and I wonder what would be the best way to align my EQ telescope when the polar star is not visible?

  • $\begingroup$ I know...I forgot to mention an important factor: I'm surrounded by mountains that block my northern view for like 20°. $\endgroup$ – betolink Aug 12 '14 at 21:50
  • $\begingroup$ Sounds like you need to figure out where due north is and aim about 4° below the top of the mountains. If I knew a good way to do that I'd post an answer, but a compass, a level, and a protractor might help. (Polaris is about 1° off the celestial north pole anyway.) $\endgroup$ – Keith Thompson Aug 12 '14 at 22:04

Mount a camera on the tripod and take a long exposure. You should be able to determine the concentric circles of the stars paths. The center of the circle is the North pole.
