You'll need to wait a bit but check out sigma Orionis, a quadruple. Nearby is a nice double, Struve 762. I was surprised at the appeal of doubles. Clear skies and good hunting.


Actually, the quintuple star Sigma Orionis is Struve 762. Struve 761 is the nearby triple star.

Wow, I can't believe no one has mentioned Algieba, gamma leonis. One of my favorite double star experiences was viewing it through holes in the clouds and a light rain falling. With an 80mm refractor it was simply stunning, yellow-green!


In addition to Gamma Andromedae and Gamma Leonis, two noteworthy "gamma" doubles are Gamma Delphini and Gamma Arietis. Gamma Velorum is a fine multiple star.

Iota Cancri is a colorful springtime double. The Winter Albireo, h3945, is another very colorful binary star.

One of my very favorites, however, is Struve 2470/2474 in Lyra, the so-called Other Double Double.

Wow - for every season there's at least a handful. For summer:

61 Cygni
Albireo
Delta Cygni
Trifid Multiple
Zeta Herculi
Epsilon Lyra
Double-Double-Double in Lyra
Es244 in Cygnus
2EsVulpeculi

There's more but that's what comes to mind.

My favorite is Gamma Velorum. Its multiple star system is symmetrical and looks like a dragonfly.
WZ Cas is a lovely red-blue
Es244 Past Thread Link
STF 1659 is the Stargate cluster in Corvus

I always give Polaris a close look. If you can see the companion at low power then you know it's going to be a good night.

I stayed up late and caught an off season view of beautiful sigma (oops: ETA!) Cassiopeiae: easy to split and interesting color contrast: bright pale yellow and dim red.
Another pretty "gamma" is Porrima, in Virgo: it used to be a difficult split, but now the separation is wider and 100x or so will split it.

Years ago a music reviewer said that his favorite Haydn string quartet was the last one he listened to. My favorite double star is the last one I've seen thru the telescope. Paul Couteau said (paraphrasing): "The sight of a [any] double star through a telescope never leaves you indifferent"

My first was polaris, I was amazed when I saw my first with my own eyes. then I saw iota cancre, loved it but couldn't get a good photo becuase I sucked at it then. But rounding out the blue/yellow is Albireo.

I got a great picture of it, one of my best. The colors is what I like about it. I had a good friend as a kid who always wore the two colors together so when I see the colors together it brings be back to a godo place in time. thus tehy hold a special place for me. like th good memory is cemented in teh heavens. The pic I got was only adjustd levels and curves the colors are what I take pride in trying to capture the exact color with out adding to it or taking away. that is my drink of choice. It has to be true to the object and do it justic. My pic is in my gallry but in the thread in this corner. (I am taking note of the ones mentioned I want to get a double and tripple collection going.)

Rigel for me. Easy to show others who are amazed at the size, (that is the brightness) difference between the two.

In winter time, an easy and great looking triplet is Alnitak (zeta Orionis), leftmost in the belt.

... and the easiest way to catch a white dwarf: 40 Eridani, easy to locate and view, near Orion. The mag 9.5 star in that triplet is a white dwarf, way easier to see than the "pup" Sirius B!

I just bagged this one yesterday! Nice, tight pair, both looked white to me at 150x (XW 20 + TV PM 2.5x) in the XT8g. Classic '8' shape, riding each other's diffraction rings! The seeing was very good and the scope was well cooled down, I might add. Upping the power to 300x+ (Nagler Zoom @4mm), they looked like a light yellow, equal pair, with a bit more separation.

My current fav is alpha Herculis. Nice coppery peaches and cream and plenty easy and brilliant at 70x.

Bingo! For me, that's lambda Cygni--beautiful 0.9 arcsecond split at 490X in my 12.5. Secondary basically due north of primary. (But I love all the ones mentioned above as well.)

Now Izar is below the trees, Almach is my favourite.
As it is a closer double than Albireo and with similar colours, think the contrast is more striking.
