Does anyone have a older Norton Star Atlas. I have heard there is a version that uses different symbols (other than varying sized dots) to represent different magnitudes. Is this true. Or is there some other Atlas like this?

How old do you mean by older? Mine is 1973, Epoch 1950 and uses the filled in circles (although some have open triangles and circles in the centers) to indicate magnitude.

Actual I now know older than 1973. I had just heard about this and never seen it. I was curious as to how such a system would work and look. Thanks for your answer. What star atlas do you like to use?

I use the Sky Atlas 2000 although I don't really "use" star atlases anymore with the advent of the personal computer. Still kinda like them, though, in an abstract way.

I have an old version in my library at home but I can't recall when it was published so I'll have to check. I have a 1989 Norton's 2000.0 edited by Ian Ridpath with me here at work that I sometimes refer to. The work is handy is what it packs in to a compact reference source though I must admit I too use software mostly these days.
Several of my older astronomy books are interesting in that they predate the discovery of Pluto or the resolution of the debate about galaxies.
