Iota Cancer - Colourful Double Star

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.

Bob this is one of the all time great doubles ...Iota is easy for beginners to try, as is Cor Caroli..and your 115mm Vixen would show their amazing colour contrasts perfectly...that 115mm is such a useful size Astro weapon.
