The colour of double stars, a tricky business!

Yesterday I published my first observing report on double stars in the deepsky section of my website. I got a lot of positive reactions, and many people asked me about the colour of the stars. Well, I think that identifying the colour of double stars is a tricky business. What colours you see when observing double stars depends on many different factors like the quality of your telescope, eyepieces, but also the “quality” of your eyes. There’s an interesting article on the Internet by Paul Baize, introduced by Andrew James, called “Notes on Double Stars - Baize Colour article”. Just follow this link and read the full story. Maybe then you understand why I think that the colours of double stars that we see through telescopes and binoculars are highly subjective!
