Red stars

Hello all, I am trying to work up a powerpoint presentation for my local astronomy club and thought of Red Stars. I think maybe to avoid red dwarfs and concentrate on fairly easy to observe Giants and Supergiants eg Betelgeuse and mu cephei both of which are easy to locate.
Any suggestions for some other candidates would be welcome. Also any good links for info on these stars and other red giants.
I have of course done a bit of searching but all help gratefully received.
Cheers, Jim

Rho Cas (somewhat yellow)
R Lep (Hind's crimson star0.

Just to make a point about red dwarfs Jim. According to a SKY & Telescope article some years ago, these stars are not really red, despite the many artists' impressions we see of them portrayed as red. :wink:

Thanks for the suggestions. I actually have Antares and Alpha Herculis on my list and re red dwarfs I am aware that not all as red as pillar boxes :D
I don't expect to make my list exceed ten.
5 ori and R lep for sure so thanks again.

If one compares them to the red lights on aircraft, one can see that they are not really red.
