Astro light pictograms People not familiar with stargazing often know nothing about dark adaption and how important it is for nighttime observations. When designing the Grossmugl Star Walk Installation, we came up with a set of pictograms illustrating a sensible use of light. Visitors are encouraged to use red torchlights which preserve the eye's night vision and especially to avoid headlamps or bright white light sources in general. For use at star parties, in public or private observatories, at astronomical events or even in your backyard the pictograms are available for free download.
