Sunspot AR2670 August 4th, 2017

Last Friday (Aug 4th, I decided to see whether the current large sunspot (AR2670) could be seen through the forest fire haze. (This current sunspot is the remains of the massive AR2665 from 3 weeks ago.)  In white light the view was blurred and the camera image was worse, but in the Hydrogen alpha scope lots of details were still visible and I took this image. The area of extreme activity surrounding the sunspot is fairly easy to see, as is the spot itself. The groupings of prominences were a pleasant surprise too. The image was taken at the observatory at noon with a Lunt DS60 and Chameleon camera, it is a stack of 100 images.
