Light Pollution : Asterism

Light Pollution : Canis Major Light Pollution : Orion

Wed. May 1, 2019 – Happy May Day – be it of the traditional It’s Spring! style of May Day or the 20th Century Workers Unite! style of May Day.

Even with education, activism, and communities making an attempt to keep the skies in the American West dark, the switch over to more energy efficient lighting on and around homes and in street lights have made communities brighter than ever at night.

Two of the ‘rural’ dark sky spots that even a few years ago I could be astounded at how many stars I could see from a house or yard now are nearly washed out with too much light. Two days ago, I asked one of my brother’s neighbors to please turn off their front patio lights when they go to bed, kindly last night they did so but to little avail.

Rather than doing the currently fashionable photography trick of processing an astrophoto within an inch of its life to have an incongruous scene of lit foreground object with AMAZING Milky Way Photo, I have instead processed these photos as my eye saw them.

How did my eye see these two adjacent scenes last night? Bright street lights casting light domes to light up houses and to wash out the night sky to the point where one only really sees the bright stars in a constellation. While the asterisms were clear, but the detail was scrubbed out.

Please folks, go read the resources of what average folk and cities can do at the IDSA and let’s work at making sure that all of us can see the stars on a clear night.

Let’s wipe out light pollution.
