R207 Double star Musca
25cm x363: Brilliant pair but quite close. Split but difficult at x276, no problems at x363. Both are cold white or bluish – close, 1-1.2" in PA 30, only 3/10ths of a magnitude in difference between the components, 3.8 4.1?? Very beautiful. Showpiece.
A measure I saw elsewhere on the net in 2007 was 1.0" in PA 50. Apoastron was in 1954 at about 1.5" and they are currently slowly closing.
Hope that helps.
Best,
L.

Thanks for including your observing notes Les! Beta Muscae sure sounds lovely once split! Great job resolving it, armed with your knowledge I will try to split it again on a night of "perfect" seeing. Thanks
