Chromospheric active stars: a key program for amateurs

Hi Christian

I use a Lhires III, but with 35mu slit....

(slight loss in resolution but more throughput I guess)

I'm late to this project but certainly interested in participating, with my eShel2, if southern stars are of interest.
Is there a list of possible southern targets, visible from latitude -37 deg?
