Steve's Notes

===== NGC 4909 14" (4/2/16 - Coonabarabran, 160x): faint to fairly faint, small, round, 25" diameter (this is the central core region on images). With averted vision increases to ~40" diameter. A number of stars are nearby including a pair of mag 13 stars [11" separation] 1.6' SE and a mag 11.5 star is 2.3' E. In addition, a mag 12/13 pair at a similar separation is 2.9' SW. The latter is part of a distinctive arc of stars that begins 2.5' SW and sweeps clockwise, ending at mag 10 HD 113176 7.7' SSE.
