Description

The very large sunspot group AR2192.  This was large enough that I could see it easily with the naked eye (behind a Baader solar filter).  The framing is poor because I couldn't see the laptop screen very well in the sunlight.  I used a blue filter in addition to the Baader solar film to further reduce the signal, and it gives a little contrast increase as well.  Dark subtraction and flat field applied
