Sunspots, September 7, 2014

The smaller group (first photo) is sunspot 2158, which released a CME a few days later when it was directly facing Earth. The larger group in the other photo is sunspot 2159. Both are false color images. The resolution of the convection cells approaches that obtained using an H alpha solar filter, and is much better than any solar image I've previously obtained, which indicates that the seeing was unusually good that morning (or that I've finally learned how to run my equipment). Both images are full resolution, at the same scale.

my back yard; September 7, 2014, 11:00 - 12:00 AM, T=+20 C. Celestron NI5 on 150mm refractor with 2X Powermate; Baader solar filter. Both images are Registax stacks of the best 6% of combined videos (2158: total of 362 frames; 2159: total of 883 frames).
