Well I have seen it split in a 60mm spotting scope
with 27X magnification but I doubt whether 10X will be enough even if you have
the binoculars mounted and stable, but your mail does say that you were trying
to Identify the star, this is strange as Albireo is an easy Naked Eye object, so
in Binoculars it should be no trouble at all, if you have access to a PC
planetarium program such as Skymap (you can get a free demo from www.skymap.com ) you should be able to print
out a chart of the region showing stars down to mag 8 which will help you find
the star in the binoculars a little easier. Hope this is of some use to
you.
