WZ and Struve 254 are always crowd pleasers at public star parties. Beutiful color contrast!!

ITs funny WZ is getting all this attention and thats a testament to the power of the internet.
Agreed! It's really an amazing thing to be able to so readily make exchanges between the contents of each other's minds and compare experiences over such tiny (from within *our* world), *extremely* obscure points of light!

After looking at WZ Cassiopi and U Cygni, WZ looks more orange than red to me, while U Cygni does appear a deep red.

Looking last night, I found WZ Cassiopi and U Cygni a similar shade of red. This was under a very bright moon. I also took a look at the Garnet Star and V Corona Borealis which both look more orange/gold than red. T Lyrae is the deepest red I've seen so far.

I just to see by very first time Otto Struve 254 (WZ Cassiopeia) last night. Really a magnificent spectacle! I don´t know if it's was for seeing conditions, but I noted a more powerful colours at low mags than higher.
Such beauties in the Heavens hook me more and more in this hobby!

I sometimes notice that if I stare at a star for 10 seconds or so, the color seems to intensify, especially the yellow part of the spectrum. Sometimes a star will even turn from yellow into a more yellowish-orange in color.
Of course, everyone's eyes are different when it comes to seeing colors.
Like you, I sometimes notice that colors will be more intense at low power compared to high power (ie. 33x/160x)

Thats the perkinje effect. Theres neat experiments that can be had on this in color perceptions through different lighting conditions as well.

Anyone notice there's another double with a red component in Cass? I saw it a few weeks back, it's near the other end of the "W" from WZ, and I don't have any charts here in front of me, so that's the best I can do on location for now.
Maybe someone could give us an exact coordinate and name. I think looking at the PSA at the time, it wasn't in there as a double. (Of course, my memory could be flawed after all this time).

I just nabbed WZ CAS this Wednesday night, very nice indeed. In addition to that I saw V AQL, which was a red, single, but red carbon too.
Same night, I saw the following (Intelliscope names)
V AQL (red)
A CAP (Golden, w/1 blu and 1/wht)
Dapith (white w/blue sec)
CAP Omnicron (Wht pri, w/yel and wht/blu secondary's)
CAP Pi (vry tight w/wht primary and wht secondary)
CAS Epa (brt wht/golden primary and bluish secondary)
Having great time with doubles!

I do!!! Actually, at the begining I confused this pair with Otto Struve 254. But that pair has its components a little more apart and is fainter, is it?
I think it is a little more towards Caph, but i must confirm it.

It's been a while since I've been able to be out (lousy weather), but I dug out my PSA and I think I remember where I saw the other red-component double in Cass. Maybe someone can check it out?
I believe it was either HIP8362 (about 1/2° west of Epsilon Cass), or HIP8626 (about 1° NNW from Eps Cass, also listed as Struve 163).
I was out starhopping through Cassiopeia's clusters when I came across it. I remember thinking how fitting that it should have a red/blue double at each end of the "W."
I'll try to look for it again next time I'm able to be out, but from the looks of it, it might be a while.

Hi Tim,
From your description I believe it is HIP 8626 (Mag 6.5) @ RA/DE 1hr 52' 0"/+64°54'11" (1.25°NNW of Epsilon Cassiopeiae) with a red/orange hue and HIP 8632 (Mag 9.15) with a light blue hue. This pair is an optical double. HIP 8626 is ~163,000 lyrs away with an absolute mag of -11.99. HIP 8632 is much much closer to us. This pair is Sigma 163. I observed this delightful optical gathering with my ST80 tonight @ 29x. Nice color contrast for sure.

Hey Patrick,
Yes, that's the one! We finally had clear skies last night after weeks of rain and clouds, so I got to check it out again.
I went back and forth between it at WZ Cass, and they are similar. I think WZ's red is a little deeper, and its blue looked a little brighter to me.
I think it's cool that at each end of Cassiopeia, at about the same close distance and direction from the constellation star at that end, you can find a nice red/blue pair. Especially when they don't seem to be all THAT common in the sky.
I think these two doubles will be regular stops for me whenever I'm touring Cassiopeia!
Good hunting to you!

I took another look at WZ Cas last night. It had a quite deep red hue. It really stands out in the star field when you get it in the field of view. My own call was Mag 6.6
