Should the mount be tracking during polar align

Should your mount be turned on and tracking during the polar align routine or does it not matter? I'd think that it should be on for best resolution of the stars used for plate solving but was just wondering.

Hi,

it really doesn't matter – typically you will be taking 2 second exposures (or some fairly similar length) and you are taking images very close to the celestial pole. The combination of the two means that you will get no visible star trails regardless of whether you are tracking or not. In fact the total rotation would be very small even during the whole polar alignment procedure (which typically might take a few minutes).

Cheers, Robin
