Spectroscopes come in all shapes and sizes, a bit like telescopes. Some are designed to be better for obtaining stellar spectra, others are made for solar and extended objects such as planets, nebulae, and deep sky objects (DSO’s). Spectroscopes are based on using prisms, transmission gratings, or reflection gratings, and depending on their use, they may or may not include an entrance slit.
