A red flashlight is one of the most beneficial accessories you can own as an amateur astronomer, no matter how occasional your night sky observations may be.  

Also, if you plan to observe with other people, whether at a star party or in your own neighborhood, a red flashlight is an important part of good star party etiquette.
