Over the years, I've looked at Albireo countless times and have gotten its separation engrained in my mind.

I recently went looking for it with binoculars out at a dark sky site and nearly logged it, when I realized I was looking at the wrong star pair!

Near Albireo is Alpha Vulpeculae which looks just like Albireo does in a telescope! It even has roughly the same color contrast, just not as intense to my eyes. You actually can get both Alpha Vul and Beta Cyg in the same FOV of a 6 degree FOV binoculars, with Albiero clealy being the tighter pair.

Alpha Vul is a pretty optical pairing at 20x. I was in Vulpecula with my 5" sct a couple of nights ago and gave it a look-see. I'll see if I can get both Alpha Vul and Beta Cyg in my 8x42's tonight. It's clear and cold here tonight. :jump:

I can't say for sure that I've purposefully looked at this corner of the sky (observed Albireo dozens and dozens of times).

Next chance I get, I'll take a look for alpha and 8 Vul (aka STF A 47). WDS lists it with a 2012 separation of 426.6 arcsec. Definitely a low power pair, let alone getting Albireo in the FOV. Thanks for the heads-up!
