Departing Filaments - 28th July

A double stacked setup is a great way to improve contrast when viewing in Hydrogen Alpha light, as the bandpass of the filter has steeper sides and lets through less continuum leakage, which has the effect of making the contrast of features greater.  These filaments show up really well and reflect where on previous rotations there were active regions.  Once these clouds of plasma have gone in the next day the sun will be completely blank.  Taken with the Daystar Quark on the 60mm f6 refractor double stacked with a Lunt 50 etalon.  Camera was the PGR Ch3.
