Heinze 2-111; PK 315-0.1Planetary NebulaApril 14 2007Belanglo 250mm f5.6 Dobsonian6mmSWAUHCAmprphous knot. Hard to see without UHC. Faint.
IC287211:29.0-62 57Emission Nebula12'x4.0'January 18 2007Lostock 250mm f5.6 Dobsonian13.8mmSWAUHCLots of faint nebulosity in the area, the largest being IC2944 (Running Chicken Nebula). What I perceived to be IC2872 contains a right-angled shaped triangle of stars.

IC294811:38.8-63 32Emission Nebula75'x50'January 7 2000Wiruna 250mm f5.6 Dobsonian26mmPlosslUHCNext to bright star lamda-Centauri. Very large area of nebulosity, beyond the field of view of the eyepiece , but obvious with the UHC.
IC389612:56.6-50 09Galaxy12.32.2'x2.0'88MLYJuly 18 2009Culburra 250mm f5.6 Dobsonian9mmNaglerVery bright. Nearby is a snmaller galaxy, preseumably IC3896b.

NGC3699; PK292+01.111:28.0-59 57Planetary Nebula11.367"July 22 2000Cataract 250mm f5.6 Dobsonian6.3mmPlosslUHCEasy to see even at low power. In a line with two field stars. Used a range of eyepiece combibations. Even a 9.7mm with a 2x Balow (288x) showed it well. Large, nebulous, slightly curved mass. Using averted vision, it is possible to detect a rift in the mass of nebulosity.
