Collinder 31616:55.5-40 49Open Cluster3.4105'June 16 2020 Farmborough Heights250mm f5.6 Dobsonian30mmUWAThe field of view is 1.8 degrees using this eyepiece. Collinder 316 is 1.75 degrees and within it is Trumpler 24, at 1 degree. Stretching from the very bright and much smaler NGC6231 is a line of stars leading to an apparant Y-junction each branch leading to separate concentrations of stars; one elongated and one more compressed. NGC6231 is to the west, the elongated group south and and the compressed group north. The region is quite rich and stunning.

IC4663;PK346-08.117:45.5-44 54Planetary Nebula12.5>13"9.8KLYJuly 10 1999 Cataract250mm f5.6 Dobsonian26mmPlossl/9.7mmSP/6.3mmPlosslUHCAt low power, in the middle of an asterism of stars about 20' across, 3 stars on one side, 2 brighter stars on the other. I feel I could see it as a 'blinking star'. Higher power seemed to show a tenuous disc around the central star. It didn't disappear with the UHC filter.[Also Belanglo July 14 2007: Solid non-stellar disk with the hint of an outer halo]
