Favorite Stellar Double? - (whether visual or true binary)

Palomar · 2004-12-12 23:45:53

*My favorite is Albireo, in Cygnus. Of course, it's rapidly swinging out of view now (summer constellation, to the far NW early in the evening).

Two nice images (appears a bit smaller in my 'scope -- especially compared to the bottom image -- on high magnification):

*Lovely orange and blue (the secondary star appears *more* bluish in the eyepiece than it does in these pics). And yours? I know there's some other amateur astronomers here (and maybe a pro or two).

Would -love- to see Antares' little green companion but it goes without saying that my 'scope isn't quite up to tackling that task!

P.S.: Some comments by others (with better equipment than I) as to http://www.carbonar.es/s33/scorpius/Antares.html]the challenges of "splitting" Antares and its companion. (Well...except for the person with the 16" Dobsonian of course!)

Eta Cassiopeiae is amongst my favourite doubles as it was one of the first doubles I viewed through my scope (could not find it for ages - poorly aligned finder now fixed). Phi Cassiopeiae was next viewed but could not resolve that night (nor many after) I've only really seen it once on a very still night.

A lot of people are using modified web cams these days (as your second image shows) to pick up feinter objects, perhaps thats the way to go.

*It's been a while since I viewed that double.

could not find it for ages - poorly aligned finder now fixed

*Some of those viewfinders are a royal pain in the backside. Mine has no magnification at all; is basically a metal ring which is merely a part of a larger piece of metal which attaches over the barrel of the 'scope. When it's flush against the eyepiece casing (which takes a nanosecond to adjust), I'm ready to go.

*I'd like that opportunity but I don't have access to one and my 'scope wouldn't be compatible (no tracking, no coordinate circles -- pure star-hopping). If it's an attachment to the 'scope itself; I don't know much about modified web cams and things of that nature.
