Your eyes gradually become more sensitive in the dark, allowing you to see fainter stars and more detail through the eyepiece. A burst of white light can undo much of that dark adaptation just when your observing session is getting interesting.
The Astro Essentials torch gives you a dim red light for the practical jobs that still need illumination: reading a paper chart, finding an eyepiece, checking a mount scale or adjusting telescope controls. Red light is not completely invisible to dark-adapted eyes, so the brightness control matters. Turn it down until it is only just bright enough for the task.
The selector switch changes between red and white LEDs. Red is the observing mode. The brighter white light is useful while setting up, packing away, checking the ground for a dropped dust cap or walking safely after the session has finished.
Having both modes in one small torch keeps the kit bag simple, though it is worth checking the switch before turning it on near other observers. At a shared dark-sky site, always point the torch down and ask before using white light.
If you use a phone or tablet at the telescope, also enable its red night mode and turn the screen brightness down. A red torch handles the physical tasks without needing to unlock a bright screen.
