This double is described in
The Cambridge Double Star Atlas as:- The Albireo of the Spring. We will overlook the Northern Hemisphere bias relating to the seasons.
The orange colour of the primary contrasted strongly with the fainter blue secondary, which appeared to be some 2+ magnitudes lessor. The separation of the two stars was sizable, even when only using 36x with my 115mm ED refactor on 13th March.
