Actually, Dale, I wasn't referring to the Clark information at all, have never read the book. In fact, the only observing guide I've ever really used, other than the object catalogs themselves, is the Burnham 3-volume set. Was just a comment on the pitfalls of visibility tables in general, nothing against scientific methods applied to anything and everything, even when (in my opinion) unnecessary. You have to understand that I've been doing this a long time and developed observing habits long before there were many of these types of "how-to" books, or before I had the means to acquire them. Many times I've seen objects that I found out later shouldn't have been visible with that particular aperture. Sorry if I upset or mislead anyone. C. --- Dale Hooper <Dale.Hooper@sdl.usu.edu> wrote:

Chuck,

Are you referring to the Roger Clark information when you say "usefulness of tables like these."? If so, I'm rather surprised and suspect that you haven't looked at the information very closely. There is a wealth of info in those "tables", other parts of his website and his book. The website and his book present better ways to be prepared for "the hunt" and how to get the most out of observing "the kill". Its a bit of a disservice to pooh pooh this information just because Clark applies the scientific method to observing. If you aren't referring to the Clark info - then my apologies.

Also, I didn't really take it that Brent was referring to the Clark info.
