Hi Sebastian,
If you haven't already got these items, I suggest you purchase them.
A "Chandler" (large variety) Planisphere.....About $20 from Bintel, Sydney. (Binocular & Telescope shop.)
A red LED torch. Your choice of hand held or head-band. (I bought an Acme brand torch from Woollies for $3.00 odd, with AA batteries.)
This will save your night vision.
A comfortable folding chair for those long nights.
Lots more to come..........
Enjoy the night sky & all it offers.
