As a reader of this blog, you’ve seen many cool images shot by astroimager John Chumack. Here is yet another — a fabulous Sun image John captured December 11, 2011, showing a full range of solar activity, prominences, filaments, plage, and sunspots all in one picture!

John used a Lunt Solar LS60 scope with an LS50 Hydrogen-alpha filter, a DMK 31AF04 Firewire CCD camera, an exposure of 1/483-second for surface details, 1/30-second exposures for prominences, and stacked 4,616 frames for this five-panel mosaic.

A great New Year’s look at the star that powers our solar system!
