      325,000 km long solar filament group

      Dataset uses 3 panels to capture a 325,000 km long quiescent filament group on the Sun. Quiescent filaments are long lived, relatively stable cool plasma suspended over a polarity inversion line. Seeing was 4/5. A good deal of structure is visible. To create this image you will need to process and then photomerge 3 separate captures.
