Sun in H-Alpha


This afternoon I took some time to observe the Sun in H-Alpha. No sunspots but some huge filaments could be observed. When comparing the two pictures below you can see how dynamic the filaments are and changing geometry. Both pictures taken with Nikon D7500 on SolarMaxIII 70/400 f/5.7 double stacked. Pictures are converted into DNG and edited using CS4.
