Preserving Pointing Accuracy

Pointing accuracy refers to how accurately the mount can point to a target in the sky, given its RA Dec coordinates. Pointing accuracy determines how accurately mount can perform GOTO, alt-azimuth mount tracking or identifying an object. To have good pointing accuracy, build a good pointing model by performing [Alignment] then [Sync].

For pointing model to stay valid, three things need to stay the same. Specifically, at pointing time, these three things need to be the way they were at alignment time. The next sections explain what they are and, if they were lost, how to recover them.
