I sorta knew this stuff, but to have it presented in relation to a beautiful image of the nebula surrounding a cluster I've seen through my little telescope in the backyard really brings it home. I very much appreciate how kindly and patiently you share your knowledge with those of us who are here mostly for the pretty pictures.
I couldn't agree more! What a wonderful explanation for somebody who is "here mostly for the pretty pictures"! Thank you very much!
