Re: (IAAC) Obj: Albireo (Beta Cygni) - Inst: 102 mm f/9.8 Achromatic refractor
It's really fun to read descriptions of astronomical colors and try to
figure out (=guess, usually) whether the differences are due to actual
physical perception differences between individuals or merely differing
color vocabularies. 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. 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. ; )

>:Using 200x I can perfectly observe it as orangeish and blueish. My wife
