# Deep Space Objects — What's Out There

> The deep-space objects you can photograph: emission/reflection/planetary nebulae, galaxies, star clusters, and supernova remnants.

Deep-sky targets fall into a few families. **Emission nebulae** are clouds of hydrogen/oxygen/sulfur gas glowing at specific wavelengths (great for narrowband). **Reflection nebulae** scatter blue starlight. **Galaxies** are distant island universes — small and faint, rewarding long focal lengths. **Star clusters** (open and globular) are bright and beginner-friendly. **Supernova remnants** and **planetary nebulae** are the colorful debris of dying stars. Brightness (magnitude) and apparent size determine the exposure and focal length you need.
