Active Region 3315 in Hydrogen Alpha (single stack)
Sunspot pair AR 3315. As this is a single stack etalon image some of the white light detail of the umbra/penumbra leaks through the filter adding more detail to the sunspot.
The swirls of activity around the pair reflect the magnetic fields. Between the opposite poles of the sunspot pair is a bright transition zone with 3 dark field transition arches crossing between - this is the boundary between the 2 poles.
Single Etalon on Celestron 1000/102mm f10 refractor.
ZWO ASI290MM camera
