N5286 & M Cen


This pairing of a small globular and an orange and blue double is a favorite. The globular is a Dunlop find made at Parramatta c.1826. It's a nice observing challenge as it's not round in shape and the resolvable stars form faint chains. Some dark lanes may also be seen. A field star overlaps it.
The double star is Harvard HdO 225 (M Cen) - a yellow/orange K type giant. Is the secondary really blue? Or just a contrast effect? The planetary's outer halo of <14mg stars is hard to see -  astrophotos show a larger object than I can record. A very nice field for a scope of any size!
