The Sun on February 9, 2013
Although there are no actively-flaring regions on the sun at the moment, the current active regions show interesting structures in H-alpha. I also captured some long filaments and a loop prominence. Each image was captured with a PST/SolarMaxII and a modified Microsoft Lifecam. 1000 frames were captured for each image and the best 200 frames were stacked and processed (Registax 6). Final finishing was done in Photoshop.
