Hi Nathan

Keep at it. It's time well spent. I reckon it's worth trying a few different ways until it all clicks (e.g. polar scope, drift align, alignmaster).

If you have a guidescope and camera:

1. Get your camera aligned so DEC slews are up and down, RA left/right
2. Turn off DEC tracking in your guiding software (or download something like Al's Reticle program
3. Position star against reticle or crosshairs
4. Monitor drift (this is easier if you have a program that monitors it for you, but you can watch and time versus crosshairs too).
5. Adjust Azimuth for stars on meridian (27 degrees north of overhead) and altitude for stars near E or W horizon
6. If you're heading in wrong direction, drift rate increases, correct direction it will improve (and turn negative/positive if you go past the ideal spot)


Maxim is good for this - turn of DEC tracking and monitor graph and X guiding error. A good freeware option is K3CCDTools.

Don't be afraid to practice this a lot at home - it all becomes surprisingly difficult again when you set up in a new unfamilar dark sky site.


Let us know how you go
