What Are We Looking At?
As you slew the scope across the night sky, hopping from target to target, it’s sometimes easy to forget that each beautiful scene the eyepiece presents you with is in fact a real object. Targets for the deep-sky astronomer break down into a wide selection of galaxies, nebulae and star clusters. Before proceeding to the chapter describing where everything is in the night sky, and how best to see it, it’s worth spending a little while reminding ourselves just what these things really are.
