Hi all.
It's a longtime since I visited this forum for the last time, but I'm back.
I'm an Italian amateur astronomer specialized in spectroheliography and solar magnetography with self built instruments.I actually own five Hires spectrographs that i use in digital spectroheliography mode, with various software, and for measurement of the magnetic strenght of sunspots via Zeeman effect.
Here attached are my last works, on april, 16, 2o22. a spectroheliogram in CaIIK light and a comparison of this with two other spectroheliograms, in Fe1 and Al1 lines.
