Summing up, I think we need to have astronomy camps twice a year near the new moon in March or April and September or October.
The location should be elevated, have good weather and be within 2 or 3 hours drive of a capital city.
Bunks, toilets and showers are also good.
Clear skies can be found using the map for the month in question at:
