Hi Matt,
Welcome to IceInSpace
.
The Mangrove Mountain observing nights are held at the Mangrove Mountain Pony Club grounds (which is a Public Reserve, under lease type arrangement to 2 Equestrian Clubs - hence the aka Pony Club mentioned earlier).
It is available to amateur astronomers to use free of charge (when available).
The skies are pretty dark there, although there is a bit of light dome from Sydney and several local lights that can be avoided by careful positioning of our gear.
All are welcome.
But there are currently no amenities available.
280m above sea level, viewing is good, but dew can be a problem at times. Dew shields and dew heaters are commonly used by regulars.
There is a map and how to get there in the "sticky" section at the top of this forum.
Due to poor weather, and lack of facilities, attendances have declined in recent times. Also, short camping Astro-Trips to Bretti sometimes take regulars away around the New Moon. (Bretti is about 3 hours north of Central Coast and has darker skies, is free, with long drop toilets, pleasant river outlook, and plenty of flat space).
If you keep an eye on this forum, you may see a thread started considering a Pony Club observing session, and there is an ongoing Bretti thread if you are interested in joining us for that.
Note that there are tentative plans for a Bretti trip this New Moon, but as not everyone can get away for a few days (or wants to), there will likely be a Pony Club thread opening up shortly. Weather dependent. Or open a thread yourself asking if anyone with a key is going.
Hope to see you there or at Bretti sometime soon
Regards
