Quite a lot of us on the Central Coast and a few from Sydney come up to the Mangrove Mtn Pony Club every New Moon and is probably the darkest sky near to Sydney.
It is only about an hour and a bit drive from the North Shore and you will meet a lot of nice people, all keen amateur astros.
We are trying to get another night in this coming Saturday night and you would be made very welcome.
There are posts here on IIS on how to get there and who will be coming.
Be good to see you there and as they say the more the merrier.
Cheers
