Re: (IAAC) Obj: Albireo (Beta Cygni) - Inst: 102 mm f/9.8 Achromatic refractor



Luis,
Greatly enjoying your double star reports.  I also see Albireo as orange and
blue, although I have never heard the color red referred to... but I have
heard topaz or golden yellow.

:Description:
:It's not strange that everyboy speaks wonderful things about this double
star.
:The main component appears yellow-orangeish at 25x, while the secondary
shows
:blue or blue-greenish coloration. This contrast of colors is amazing. Of
:course, it's one of my favourite double stars.
:
:Using 200x I can perfectly observe it as orangeish and blueish. My wife
sees
:the second component as red, not orange. Maybe women had a "shift" towards
red
:or men have a "shift" towards blue. I'm not sure of this. Probably the
:perception of color is something that *always* varies from person to
person.
:
:Without doubt the best view is obtained at just 50x. Albireo appears as a
King
:and a Queen in the middle of the wonderful star clouds of Cygnus.
