The seeing really wasn't up to muc, but it did give me a chance to play with the setup and tuning of my calcium filter, which gives improved contrast now. Taken at 60mm f16, when the tuning is right on the filter the contrast really pops out, making the surface darker and the bright points brighter. The chromospheric fringe and prominences are also easier to see when the filter is on band.
