patriotic triple?
|
hello
after a night of observing faint planetaries
i slewed to 31 cygnus and almost fell out of my chair due to the brightness and color (8" SCT 24 pan). the primary was burnt orange, the secondary (30 cyg) looked white to me and the close 3rd star was pale blue.
decided to snap a few pics with careful color balance and the secondary showed a faint blue halo as well, which makes sense given it's spectral class, A5.
somewhere i read a description of someone coining this as the patriotic triple, but i can't recall where i saw it. does anyone have any more info on this?

Actually, the triple is Omicron-1 Cygni, which I once called "the Patriotic Star", in one of my observing reports, so perhaps you read one of those. It is a pretty triple star (30 Cyg, 31, Cyg, and HD 192579) with wide separation, but the alignment is probably optical only, as the three stars are quite distant from us and from each other. The star field is also fairly rich, so it makes a good target. Clear skies to you.

That is one beautiful image! The companions both look slightly bluish, but the fainter one has more saturation, so we get the "red-white-blue" effect with the three stars visually. Clear skies to you.

Michael Covington refers to the "Patriotic Triple" on page 208 of his book, "Celestial Objects for Modern Telescopes" (Cambridge, 2002) but he doesn't claim to have named it. This is the earliest reference to the name I know of, but that's only a few years.

I believe the name was officially changed to "Freedom Stars" several years ago.
In honor of the 4th of July I took a look and it was great in a 4" refractor, thanks for the image!

Hi all,
Just want to thank both of you for pointing out this beautiful triple. After two weeks of rain and clouds I finally had a clear night to view them. Using the 102mm f/7 Astrotelescope and the Hyperion 24mm-8mm zoom they were absolutely gorgeous.
My Tasco Cosmic 50mm f/12 and a 22mm Meade Modified made them appear as tiny jewels in the FOV. I also used the 12.5mm Meade Modified and the tiny jewels were framed perfectly. However the color of the blue star was a very pale blue compared to the 102mm.
Well worth the price of admission!
peace & clear skies,

Truly one of my favorite objects. Thanks, guys. For some reason, though, I have always thought of it as gold, white, and blue. Nonetheless, it is a beautiful sight. Found it by accident last year while scanning with my 10x50s. I have also heard it called "the bino Albireo."

"Objects in the Heavens" by Peter Birren, Naoyuki Kurita, 1st edition 2002 also mentions it by this name. Would be interesting to find out the very 1st use of the term for this star.

In my 8" reflector, these have always looked gold, blue, and turquoise to me.
I almost fell over the first time I saw this beautiful triple! To me, they look best at lower powers, like Alberio does.
