Last night under bright moonlight I've made my first observation of Beta Monocerotis. It is really wonderful star, one of the best in the winter skies. One thing puzzled me when I checked Beta Monocerotis in Cartes du Ciel - all components are blue but in eyepiece I saw slightly creamy yellow stars. Is this color mismatching result of bright moonlight or somebody else noticed yellow color of this amazing star.
Thanks

Thanks Asteroid7
So it is a tricky star, blue when unfocused and yellow when focused. At least I know that my focusing is good.

Color is in the eyes of the beholder and/or as tainted by the optics. They look blue/white to me in my newt.
