Ohio astroimager John Chumack sent this phenomenal Hydrogen-alpha that he shot of the Sun July 3, 2011, that shows a magnificent prominence towering over our star’s limb. To capture the shot from his backyard in Dayton, Ohio, Chumack used a Lunt 60mm/50F Hydrogen-alpha solar scope with a DMK 21AF04 firewire camera, and a 2x Barlow lens.

The image combines 654 frames. Chumack exposed some at 1/483-second for the Sun’s surface and the rest at 1/45-second for the prominence.
Nice shot, John!
