I recently bought a secondhand (Celestron branded) G11, and am very

pleased with it. However the view throught the polar

alignment 'scope bears no relation to the description in the G11

instruction manual. I appear to have a dual Northern & Southern

hemisphere version. In addition to Ursa major and Cassiopea it shows

what looks like Crux, and a line to alpha Eridiani, and several

other dotted and full lines that don't seem to correspond to

anything I can find on star maps of either the North or the South

pole.



Especially it doesn't show the 'second star' referred to in the

manual, so I can't do a two point alignment, which would be

preferable.



Is there an annotated picture of this graticule available please, or

maybe a fuller explanation?



Thanks
