I am new to the group and have just purchased a g11/g2 for toa 130. Main viewing will be southern exposure without access to polaris. I'd appreciate any advice on best methods for alignment. What is best method to achieve true north, and is calibrating alt on mount per gps sufficient for visual tracking--not into astrophoto at this time, just visual. Migrating from fork mount go to so all this new to me. Please direct to appropriate links as well tis

thanks

Tom

There is a pole align assistant in the Gemini 2 menu at the startup you can use. I would recommend eyeballing the alignment with a compass and taking into consideration your magnetic declination.



Some digital compasses figure that out for you I understand.



If you have a CCD camera, there's nothing better IMHO than CCDWare's Pempro. It has a polar alignment drift routine in it that I can consistently get within a few arc minutes of perfect.
