A typical use case for the 2nd led flash

The 2nd led flash could be useful for astro-photographers. It takes some time for our eyes to adjust to the darkness required for astrophotography. But sometimes we may need to find something or may need to adjust the telescope in darkness which requires turning on flash light. But white flashlight spoils our adjustment to darkness. In this case a red colored flash could be useful, red color light does not effect our adjustment to darkness so much while serving the necessary purpose.
