>Polaris is only 0.34" from the center of the screen. It has the same

>If you go to these stars using Goto|Star|Common names|... you'll find their
>distances from center are the same: Sirius 7", Polaris 0.3". However, if
>you use the Goto|Star|Bayer/Flamsteed... route, Alpha Canis Major (Sirius)
>is 19" from the center, as opposed to the 7" found above. Alpha Ursa Major,
>(Polaris) is 6" from the center, as opposed to the 0.34" found above.
