2020 July 12 Sun - prominences on the SW solar limb

2020 July 12 Sun - prominences on the SW solar limb I am showing the prominences in 2 wavelengths, if possible. In general, the prominences are much brighter in H-alpha than in Ca-K, despite the much larger aperture (80 mm f/6.25 vs 35 mm f/11.5) used for H-alpha. Sunspot count: group=0. sunspots=0,...
