Hydrogen Alpha Prominences

A Lunt composite of the surface and prominences seen in the natural red of Ha light. The surface image had the tones inverted to cause the edge of the disc to brighten towards the limb and prominences. This allows them to blend more easily, and gives filaments over the surface the appearance of being above. They don't look like this when they are dark against a brighter surface - 25-09-16.
