Found myself fading after
all the early morning viewing so went for a rather easy one. I could split
this at other powers, but enjoyed the view best in the LE. A bright, yellow-white
primary with a dimmer reddish-brown secondary.

A=3.46 very light frothy
yellow
B=7.24 dark tangerine... the color of Mars when it's just rising No need to consult the finder

One
of the favorite sights in Cass. My lack of color palette will only describe
the stars as yellow-white primary and small orange-red secondary. The WDS
lists a half dozen faint outliers to the main event, but these will remain
for another day. Measurement: 13.0 sec at
317.7 deg PA.

A really beautiful double
star. It’s rather bright and exhibits a nice white and orangeish colors.
A showpiece in Cassiopeia that deserves a place in any “demonstration list”
of doubles.

Well known binary, is a
beautiful and bright object for small telescopes. Primary yellow, the companion
looks reddish although the color is difficult to detect with this scope.
Easy, well split at 48x.

Easy at all powers.
Exquisite x120. Yellow and purple. Discovered by Sir William
Herschel. The colour of the companion has always interested me.
I have examined this pair in several apertures since 1984, reflectors as
well as refractors, and I nearly always see the colour of the secondary
star differently. Tonight's view reminds me strongly of the first
time I ever saw this pair, back in the 1980s, when I used a Japanese 3-inch
refractor. Now, as then, I see the comes as a deep purple.
Admiral Smyth also has the companion as purple, although he described the primary as "pale white", whatever that may mean. In fact, the main component appears quite a deep yellow hue. According to Flammarion, the pair is yellow and lilac. Webb saw it exactly as I do, namely yellow and purple. He also reports the descriptions of several other observers. Most saw the companion as one shade or other or red. Probably inadequate aperture explains why those of us who use small telescopes see it as purple - a spectral impossibility. This is one of my favourite doubles, a grand sight in any telescope. Ambience: Warm, still.
The night air fragrant with the scent of our two flowering buddleia bushes.

18
mm Ortho----------------This looked to be a very nice double star at this
magnification ( X67 ). The primary appeared to be yellowish with a dull
orange companion. A nice view with some fainter stars scattered throughout
the fov. HS rating 1
Note-------I observed this project double on 13 July 2003 at 01:10 hrs UT using my f/15 4inch refractor at X167( 9mm Ortho ). I noted the colours of the pair to be pale yellow and pale orange. A few faint stars were noted to appear, and then disappear, from view due to high drifting haze. One to return to under darker sky, with better conditions. Measures: ( Drift method ) From an average of 15 transits, A-B had a position angle of 318 degrees. The separation was much more difficult to determine but was estimated to be 13.5 arc seconds. Ambience.
