I had a look at R leporis, W ori and the winter albireo (h3945) last night.
For red stars, R leporis definitely had the best colour, being richer than W ori, but the latter is nevertheless also a good subject.
The winter albireo (we should really call it the summer albireo) is delightful as a contrasting double - putting the pair slightly out of focus so that the discs of light are muted in brightness and overlap really shows up the colour contrast. Thanks for the tip on this one.
Don't forget to make a note to look at EsB365 near beta crux though when the opportunity arises, for those of you who haven't seen it - it is without doubt the reddest in the sky (b-v 5.8) - not just orange red but ruby red. The reason it doesn't get much publicity is that it is not visible from the northern hemisphere.
Cheers,
Andrew
