The sunspot group to the right is the same as the group in my image from March 25. Despite calm, cold morning skies, very careful focus bracketing, and twice as many frames, this image is not quite as good as the earlier one. Clearly a case of beginner's luck, but the very high ISO setting for this image may have been a factor.
