Today I want to talk about how celestial objects are mapped and located in the sky by astronomers and telescope wielding enthusiasts. It is really not all that complicated, it is much like terrestrial coordinates except mapped out to the sky onto what is called the celestial sphere. I’ll try to keep this as short as I can, but there are several terms that will need explaining. Yes, I’m going to require that you read again. Ah, I can hear the groans already.
