Re: new spot and intens prom in several freq

WO apo 66mm F5.7
I think Mg is good both visually and photo
I use polarizing filter for more image contrast
of course proms are almost impossible to see in all other wave lengths except Ha , Hb

unless they are flare types

I was happy that I did pick up prom in Mg although very faintly

Re: new spot and intens prom in several freq

easy to see even more than caH line


the spectrograph verifies what mg filter sees and visa versa
