Jenni Kay FRAS The following observations were made with a 12.5” f/5 Newtonian, form my semi-rural home site at Lobethal, SA. The skies here typically have a limiting naked-eye magnitude of 6.1, with the seeing rated at ANT II-III.
Longmore 5 : 11 13.9 –47 57 (Centaurus)
120X: Obvious enough, as a faint, large, round, hazy glow. Much improved with the UHC filter, showing a bright, doughnut shape, 3.5’ in diameter. 240X: Relatively bright annular, with a faint star at the centre, which may or may not be the true central star. Seems to be a little brighter along the western edge. 360X: There can be seen some six stars around the rim. Some catalogues place this planetary some 8.5’ too far south.
