Celestial Objects Catalog

e2m2a

Does anyone know some good websites that give the equatorial coordinates of celestial objects: double stars, nebulae, clusters, galaxies,planets,etc.? Especially any that allow you to first pick the object. For example, I put in the Andromeda galaxy and it tells me its equatorial coordinates.

Thanks in advance.

Wikipedia is pretty good for this IMO. Otherwise, a Google search will usually find the coordinates very quickly. Is there a particular reason you want the data to be on a single website?

Convenience. Much easier to go to just one website to get a general catalog than having to go to multiple sites to look up different celestial objects.

But then I guess I could create a favorite folder where I put every website in.

Thanks for the info.

There's a program called Starry Night ( with a free open-source counterpart called Stellarium). They show you a map of the night sky at a given time and place. You can put the cursor on an object to get its coords, or search on an object. They are both pretty nice programs.

Thanks for the info.

Warning!!!! Just went to the Night Sky website and my Avast software detected and blocked a virus!
