Images taken with a 80mm Lunt Solar Telescope and a Canon 700D camera with a 2x barlow lens, 30 images stacked in RegiStack6 and processed in PS CS4.
The colour image is the H-alpha colour as seen in the solar scope and is a composite of two images one for the disc and one to show the prominences.
The black and white image is not a composite; I captured it with the same camera but used the Monochrome setting…I find it gives more delicate detail in the prominences. (East is to the top and West is to the bottom)

A dark, solar filament hovered above the Sun's surface, extending across more than half the Sun (Feb. 7-10, 2015). If that filament were straightened out, it would be more than 533,000 miles long (1,000,000 km), longer than 67 Earths.
These images were taken in a wavelength of extreme ultraviolet wavelength of light of material heated to about 60,000 degrees C. Filaments are cooler clouds of particles tethered above the Sun by powerful magnetic forces. Though this one has been fairly stable for many days, they are liable to break apart at any time.
