Valkyrie shaped solar prominence I shot this morning

....or whatever you see it as. This was the most active solar day since I started shooting 4 months ago. (at least when I didn't have clouds in PNW USA)

Stacked 25 best frames out of 500 shot in about 6 seconds. Colored orange (I shoot in Mono, may start coloring red, since Hydrogen-Alpha IS red) Frame length: 4 milliseconds each.
