I am going to use the Polarie Polar Scope for PA. The polar scope allows compensation for the actual longitude within the specific timezone. Here's my confusion:
1) When i check time zone maps with longitude - Queenstown looks like it falls within the GMT + 11 (DST would be +12) which is the longitude of 165 degrees east.
So by right, i should adjust 3 degrees East to compensate
2) However, when i check the actual time zone, it tells me Queenstown is GMT + 12 (DST +13) which would then coincide with 180 degrees East. Which would mean that i need to adjust 12 degrees west to compensate.
I am thoroughly confused and need some NZ folks to point me out.  I must be missing something really really major or just plain dense.....  |
Joyce, the whole of NZ (except Chatham Island) operates at UTC+12 in winter and UTC+13 in summer. You can use which ever of 1) or 2) matches how your clock is set.
The longitude adjustment is there to best set the orientation of the polar scope with the alignment stars at the current time. If you get it wrong what you will see is the stars are rotated relative to the engraved reticule. As long as they are consistently clockwise or anticlockwise it will still be OK.
