Dolidze 2716:36.5-08 56Open Cluster6.325'June 16 2020 Farmborough Heights250mm f5.6 Dobsonian32mmSWAIs this really a cluster? Information on the ARGO NAVIS computer says doubtful. Ten stars widely separtted in a very sparse field.
IC460316:25.6-24 28Reflection Nebula20'x10'July 20 2020Culburra400mm f4.5 Dobsonian 13.8mmSWAOIII/UHC2 bright stars, one approximatley 2-3 times brighter than the other, in the middle of the field and very little else visible star-wise. Filters reveal nebulosity around the brighter star.
IC460416:25.6-23 26Reflection Nebula60'x25'July 20 2020Culburra400mm f4.5 Dobsonian 9mmNaglerTIOIII/UHC3 bright stars form an equilateral triangle. The binary and easternmost of these 3 is a binary of approvimately 2X magnitude difference. A pronounced round nebulosity around all 3 stars but particulary the binary. Filters enhance the nebulosity slightly. The OIII filter causes the binary to appear green, while the UHC causes the 'red-dot effect' on the same star.
IC460516:30.2-25 06Reflection Nebula30'x30'July 20 2020Culburra400mm f4.5 Dobsonian 9mmNaglerTIOIIIA star sitting at the right 90 degree corner of a right-angled traingle becomes nubulous with the filter. It is the easternmost star. Other 2 stars W and S. The S star about twice as far as the W from the nebula star.
