Observed 3 times. 6:30pm to 9pm, 12:30am to 2am and 4am to 5:15am (total 5¼ hrs)

Location 8.5 km west of Lismore, NSW (28.8 S, 153.2 E, alt 45m)
Good horizons W, N and E with some light pollution on the E
Hill on the S side, but the SCP, LMC and SMC were still visible
Fog in the valley and dew on the hill where I was observing
Used a hair dryer to dry the secondary and EPs many times.

Telescope 12” collapsible Saxon Dobsonian, focal length 1500 mm (not goto)
Eyepieces 26mm (58x), 11mm (136x), 9mm (167x), 4.7mm (319x)
Used a UHC filter on the 9mm EP for large PN and most nebulae
Used a UHC filter on the 26mm EP for large nebulae (Lagoon, Veil, North America)
Also used 15x70 Celestron binoculars on the Milky Way, LMC, SMC, M31, M33

Made a list of DSO I had seen after I got home, saw about:
19 open clusters, most seen with the 26mm EP
50 globular clusters, most seen with the 11mm Explore Scientific EP which has an 82 degree apparent field of view
28 nebulae, seen with the 9mm EP and 26mm EP both with a UHC filter
Also scanned the SMC and LMC for clusters and nebulae with the 11mm EP
37 planetary nebulae, seen with the 9mm+UHC and 4.7mm Explore Scientific EP (82 degree apparent field of view)
64 galaxies, most seen with the 11mm EP
198 total + lots of objects in the Magellan Clouds

Also saw Jupiter, Saturn, Mars and Venus with the 9mm and 4.7mm EP

The 37 PN were
M27 M57 M76 Mz2 NGC246
1360 1535 2867 2899 3132
