Hi Stephen: About the granulation, David Knisely sorted me out on that one and provided enough information to fill your average telephone book. The man is an absolute gold mine of information. He feels that a 6" white light filter will show granulation, although I must admit that I have never seen it [that I know of] through my F 11.7 6" newt at left. But the sunspots look really terrific. Come to think of it, I have not noticed granulation through my 10" dob either. I'll have to pay far more attention next time. Trouble is, since I got the PST I haven't looked at the sun with the newts. Keith
