Full disk Sun in Hydrogen Alpha, CalciumK & White Light - 22-05-22


Recommended Posts

Lovely warm May day for solar imaging. There follows the sun in Hydrogen Alpha (Lunt 35) two versions one processed to show prominences and another surface detail, CalciumK (TEC140, Herschel Wedge and Altair CalciumK filter) and White Light (TEC140, Herschel Wedge). All were imaged using the Altair Astro 174M. Processed Autostakkert3 (best 10% of 1000 frames) and tweaked in Microsoft Photo.
