Well I figured out tonight what was up with my scope. I pinched my main mirror when I put the mirror back in the holder. I had collimated it correctly twice. After searching the net by images I found some that looked like what I was seeing. This lead to the explanation of pinched optics. I've read many articles on cleaning a mirror and collimating. I don't remember anything warning about pinched optics. This seems a great oversight. So here is my warning, be careful about how tight you fasten down your primary. I don't have any images to show. Though I can say that the heart shaped out of focus image is the tell tail sign. This site has a great collimation how to and includes an image of pinched optics. Wish me better luck next time. Hopefully tomorrow I'll get everything right.
