RE: (IAAC) Uranometria


Greetings from someone new to the list !

I do agree that "I don't buy a new atlas everytime one comes out", though I think that being an owner of the Millennium Star Atlas, I don't really need another one... <g>

But I seriously wonder why there are new editions of Sky Atlas 2000.0 and Uranometria. For a textbook, it's normal, since things can change, like for example our understanding of the nuclear fusion processes in a star's core. But for an atlas... They're all for epoch 2000.0, so what changes so much???

Is it to justify the new edition that they add more stars by reaching a deeper magnitude? <g>

Finally, could I ask what a "binned-star" is? I guess that it's all mags. together like mag. 3-4 are one size, mag. 4-5 another size, etc.

Ah, but the stars aren't binned in the new one!  I hate the unrealistic look
of a binned-star atlas.

Clear skies,  Sue
