When using an autoguider you choose one of those very slow rates
[x.25 x.5 x.75 etc:] as the autoguider correction speed.
This can vary for several reasons, such as how good your P.A.
is, and the focal length of the imaging and guiding scopes, also
whether you are imaging near a pole or near the celestial equator.
