Ha, Mg and Ca(K) Sun 3rd March LT

Hi

Attached are some images of the sun taken this morning.
I have also attached the spectral fit data compared to a reference standard.

Ha is the best of 11 reconstructed frames, 4 for Mg(b1), and 7 for Ca(K).

All frames 70% of full size & heavily compressed here.
As usual, 100mm f/9 imaging scope + home brew SHG + ZWO 183MM camera.
Frames selected and stacked with AS3!. Post processed with Astrosurface.

Seeing was ok, but no where near as good as that on Friday morning, particularly at shorter wavelengths. My scintillation monitor read between 2.85" and 3.2"

cheers
Maurice
