An astronomer friend made me aware of a spring time Albireo in the constellation of Coma Berenices, 24 Comae Berenices (Struve 1657) to be exact.  It is approximately halfway between Denebola and Arcturus, just beneath Berenice's Hair.  I pulled out my 127mm Mak and gave it a look and was pleasantly surprised!  It is a beautiful blue-gold double, smaller and less bright than Albireo, but nonetheless striking.  It is a variable physical double of spectral types K0 and A3 with magnitudes of 5.2 and 6.7 respectively. It is actually a triple star system about 300 light-years away:

I made a composite of the blue/gold doubles I've imaged over the years, including Albireo, at the original image sizes to compare apparent star scales and distances between the stars:

If you haven't already, check out 24 Comae Berenices; it's worth a look!

Clear skies!

This is an excellent summary. Thankyou.    

Coloured doubles are a worthy challenge for imagers with long focal length rigs and non-narrow band cameras.   ( Always good to have targets for those Moon illuminated nights).

You're very welcome, Craney! Thanks for looking :)

Great description and now added to my list of things to hunt down. The composite is a really good way to communicate the relative scales of these doubles. Thanks for taking the time to put it together.
