Whmacs,
I to own an EQ6 ver 3.12. Last Saturday night I spent time drift alingning before star alingment. Once completed (not that difficult and plenty of how to info on this forum) I did a 2 star alingment due to limited sky view and the first star appeared in the finder scope and in the field of view with a 15mm cross hair eye piece. Up until this point I had not done a serious polar alingment and the stars had to be bought into the field of view.
Lesson (1). Do polar alingment.
As to the other problem of +90 deg at park. I noticed this to but if you go to position in utility menu and press enter the top line should show RA. hour for SCP and DEC of -90, the second line shows ALT AZ of 00.00 +90. If it is polar alinged and in park position.
But do check that your time zone is set "+" and not "-".
Hope this is of some help
Regards
Brenton.
