Now for something completely different. Here is a list of double
stars whose
components show a large amount of contrast in “COLOR”.
This list was compiled
from a number of sources. The “COLOR - KEY” was adapted
from Webb Society
Deep-Sky Observer’s Handbook: Volume I Double Stars by Kenneth Glyn
Jones.
Since the color of stars, as seen through the eyepiece can be very subjective,
the “COLOR - KEY” will only serve as a guide. You may not
agree with the exact
hues in the key, but I think you’ll agree these are some real beauties.
