Re: Star Tracker alignment

If you are going to use it for UWA or WA shots then you can do a rough, estimated alignment. The wider FLs don't require as much precision in the alignment. Here is what I do:

Use a compass to find true north. Orient the tracker towards true north. Elevate the tracker the same number of degrees as your latitude. For example, if you live at latitude 32.5° N, then elevate the tilt angle of the tracker to 32.5°.

That should get you close enough to take longer exposures with a FL up to 50mm (on a FF camera). I routinely get 30 sec shots at 50mm on my FF using this method. It works better for wider FLs of course. It won't work for telephoto though.
