The sun... as it appears through the two most popular amateur solar filters. On the right, the white light view of the surface or photosphere, showing sunspots and subtle granulation. On the left is the view seen at the wavelength of hydrogen alpha light.
Only in this narrow slice deep in the red end of the visible spectrum (656.3nm) can we see edge prominences, arching filaments, hot active regions and the beautiful convolutions of the solar chromosphere - the atmosphere of the sun.
