Re: (IAAC) Obj: Albireo (Beta Cygni) - Inst: 102 mm f/9.8 Achromatic refractor
Mike,
Personally, I'm convinced that many of us who, in our
:childhoods, never graduated beyond the Crayola 24 boxes have much more
:limited color vocabularies than those who routinely used the 64 or (crayon
:envy) 128 boxes.
That's a great description! I think part of my love of observing doubles
has to do with the fact that I am an artist at heart, and I probably "see"
more colors than the average Joe or Jane . Even yesterday, while observing
naked eye with a friend, and we were watching Capella rise over the horizon
glare... I asked him what color he thought the star to be, I asked him did
it look yellow? He said maybe, but maybe also fading to a blue white, and I
noticed this too, this to me happens so much in double observing. You are
sure a color is a perfect orange, and suddenly it looks greenish! All due
to the play and mix of two colors next to each other.
I also think that I read somewhere that Saturn was a butterscotch color;
although I usually don't equate heavenly bodies with food, this was such a
great analogy. For doesn't this planet look creamy and mellow and smooth
like butterscotch, even in the scope?? It was this analogy that really got
me going on celestial colors. I say... keep those colors coming :-)
Cheers,
Penny
I don't have the book at hand at hand, but recall some
:fascinating lists of astronomical color names from different famous
:observers in David Malin's book, "The Colors of the Stars". Many colors
:there that were new to me, and a few that I'll bet are even new to the
:Crayola folks. ; )

:>Luis,

:>Greatly enjoying your double star reports. I also see Albireo as orange
:and

:>heard topaz or golden yellow.
