Sun in H-alfa and prominences


The Sun is out! For the first time this new year it was possible to observe the Sun. Obervations done using my SolarMaxIII 70/400 DS BF15 both visually and photographic. Pictures were taken with ASI224MC and Nikon D7500. Visually one promince could be observed having the shape of an irrugular arche.
