As I was setting up for the next shot, I caught a blur moving in front of the sun and took a quick shot before I had the camera lens centered over the telescope eyepiece. That results in the ugly coma effect seen here. More importantly, check out the airplane with jet contrails. Pure dumb luck. Posted by Hello

Sweet! How do you not burn your eyes getting the sun in the lens?

For solar observing through a telescope, they make solar filters that are coated with Mylar and reflect something like 99.999% of the sun's light. That's why it just has a subdued orangish color in these pictures. I should have added in the captions that the small ones are about 40x, the medium one about 80x, and the biggest one about 120x

The reflection of such a high percentage of the sun's light is also the reason that the background sky appears black.
