Many thanks, Larry. I have an acquaintance who found a mistake (which I had already corrected -- originally I'd put "arc-minutes" when I meant "arc-seconds" and had a good comment that it would be better to round off light-years when there's such a big uncertainty in distance, instead of giving the impression of a kind of precision. That happened because I the article was in terms of parsecs plus or minus half a parsec, and when I used an on-line calculator to change it into light-years it gave a strange answer that should have been rounded. Which is to say: Please, everybody, whenever I make a mistake, let me know asap. It's hard to read over your own material with a very critical eye when it's 3 o'clock in the morning and you're getting tired. Worse, I don't have a copy-desk; I have to proof material myself. (Sadly, the Deseret News doesn't have much of a copy desk with all their layoffs, but that's immaterial because I proof my own blogs.) When I know what it's supposed to say it's too easy to read a typo as if it were correct. Cory catches a lot of stuff, because she has been a professional proof-reader, but she doesn't see the blog until many hours later. Also, she wouldn't know that something that's 60 arc-minutes across is too big for this kind of planetary nebula.
