Given the rainy and decidedly unsuitable day for solar observations,this morning I dedicated myself to a work, still in progress, of showing spectroheliograms of some lines, metallic and not in the near UV.
It is a summary and a comparison of the spectroheliograms posted so far on this Forum and elsewhere.

Re: Some UV lines SHG
Thanks, Mark, but the work is still in progress: I hope to add some other interesting lines, Cyanogen are the most important, but at the very limit of QE of my camera
