    I had no idea who many double stars there were. I was in Haydes Cluster, and there seems to be a few in that cluster. I wonder if they orbit, or if they are optical only?

    I have the Cambridge Double Star Atlas, it shows optical doubles and binaries.

    I see it for $36 US for the electronic (Kindle edition). I'll check eBay for used.

    I tend to prefer the old fashioned hardcopy lol.

    Stellarium or CDC might be good if you have a desktop running Mac, Windows or Linux. Both are freeware.

    CDC definitely shows doubles.

    The true Mother-Lode of double-stars are in here - the United States Naval-Observatory:

    http://ad.usno.navy.mil/wds/

    And as fan of doubles' myself this is a wonderful outfit & website to amble through at leisure:

    https://bestdoubles.wordpress.com/

    My first serious observation of these critters were through my old 3" F/15 refractor - Epsilon Lyrae the famous 'Double-Double' resulted in being addicted-for-life! And I love showing people b-Cygni - Albiero for the first time during outreach-gathering at my local park. Might be a 'first-time' for these folks. But I wonder if it would be their last - that beautiful glowing golden color contrasted with a turquoise never fails to elicit a "WOW!" at the very least.

    Star-Pusher Dave :p

    Yeah, Albireo is a classic, it separates easily at 10 ~ 11x.

    Using the Stelledoppie website, which uses the WDS database, under advanced search you can enter a star's coordinates and a radius value around it like 30 arcsec, and it will list all the doubles around that star.

    http://stelledoppie.goaction.it/index2.php?section=2&azione=ricerca_avanzata

    Under normal search, you can just enter a constellation name and it will list everything. 5 pages of doubles for Taurus!

    As far as some nice doubles in Taurus, there are:
    77 Tau / 78 Tau
    Eta Tau
    Phi Tau
    V711 Tau
    V774 Tau

    Which telescope are you using, the XT6 or the 60mm? I have a vintage 60mm f/15 Meade that I have been using on doubles lately. It's a wonderful little scope, especially when mounted on my vintage Vixen Polaris mount - the GEM that doubles (pun intended) as an Alt-Az.

    What I normally do is look through my S&T Atlas for doubles I want to observe, or if there is chatter on the websites about particular doubles I will look at them, too. Yeah, there are more doubles up there than I could observe for the rest of my life with the 60mm, let alone my larger scopes.

    Ed,
    The Orion Dob was just ordered, and I haven't even received it yet. It'll be my new scope, that I'm pretty excited about. My 60 is old and beat up, but functional. It was left behind by my son when he went off to college. I'll likely upgrade it as well at some point.

    Had an XT6 for over ten years. You're gonna love it!

    The Stelledopie looks really good! I can see what I'll be playing with for awhile -

    Thanks!
