Sky & Telescope Uranometria 20000 atlas deep sky field guide

Just what kind of galaxy am I looking at?
How may stars are in that cluster?
What is the opacity of that dark nebula?
Is that bright nebula emision or reflective?
and, much, much more.

Uranometria 2000.0 Deep Sky Field Guide expands and enhances the Uranometria 2000.0 charts by providing precise data as to location, size, orientation, magnitude, type and much more on non-stellar objects, makin your time out under the stars far more productive.

Serious observers know that the more they know about an object the better their observing experience. An atlas can give you postion, relative size and possibly a rough idea of its shape but that might not be enough to locate it.

Take galaxies for example. A galaxy might be quite large but you could have difficulty in locating it if its surface brightness is really dim. Or perhaps is is edge-on— even bright ones like this are sometimes hard to find. To get around these problems we created the Deep Sky Field Guide to Uranometria 2000.0.
