Maybe it’s because it’s 4 am and I’m getting hungry, but all I could think of when I saw this solid split of Izar was an orange with a little blue grape beside it – beautiful.
And here we go with color perception again. John, in his more detailed report (with charts ) on Izar here, says this about the colors:
. . . Haas describes the primary as amber-yellow and the secondary as deep blue. She credits Smyth with “pale orange; sea green,” which pretty well describes the colors I see, although I lean more toward gold than green in the secondary – but I can clearly see the green tint most of the time.
Go figure! We have an “amber yellow” and two votes for “pale orange.” Not me. It was deep orange – like fresh-off-the-tree orange. In fact, more like the color of the orange that you see when you bite into it. But that’s OK. With the secondary I’m with Haas with a definite blue. But Smyth has it “sea green?” OK, that’s close to blue – and John sees the green tint but leans more towards gold? I don’t question any of these observations, of course, but it just never fails to amaze me how the same two stars can result in such varied reports.
I was using a 2.5mm eyepieces on the 60/360 – 144X. This was March 2, 2011 and it was one of the best splits I can remember of this double, an old friend.
