How dark are our night skies
So wrong have I been, what an eye opening experience it was for me the other night. My very own perception of things were wrong. What I saw the other night totally changed my perspective and processing techniques.
What am I talking about? This
What is wrong with these?
Almost everything about the skies. They are totally black. Isn’t that what the night sky should look like? Yes and No. To our eyes looking up with no reference our eyes and brain translates a black sky, but using a reference against the sky, we see a whole new perspective of our night sky, it is literally glowing throughout the sky. Try this experiment, and this requires an extremely dark sky with no light pollution. Sorry everyone who lives in a city, you will have to travel a good long distance, and sorry to those living on the east coast of the US or most of Europe, you are going to have to travel for a couple days by car or hours by plane to get skies dark enough. To truly experience this effect you will need to travel to a location that has skies rated at a Bortle Class 2 at minimum. For more information on the Bortle Classification of sky darkness go here http://www.bigskyastroclub.org/lp_bortle.html. For a link to a listing of the darkest skies go here http://darksitefinder.com/maps/world.html, this site allows you to zoom in really close. Notice how bad Europe and the East Coast of the US is? Now back to the easy provided you are in a dark location experiment, hold your hand up to the sky, notice a very dark void against a brightly glowing sky? That is air glow, the light of all those millions of stars filling the whole sky, your hand literally looks like a black hole against brilliant light (the glow of light pollution does not count, don’t try to be sneaky). Just that experience has changed my whole processing of the night sky, I always attempted to build a contrast resulting in a black sky. NO MORE from me, It is far more impressive to include as best as I can the amazing star glow I am witnessing every time I go out.
The above shot is a simple silhouette of the foreground. The sky really does glow enough to create a clearly defined silhouette when viewed against it. If you notice to the right of the center of our Milky Way are the planets of Mars and Saturn as the two brightest “stars”.
The other night I was at Vega State Park which is at the foot of Grand Mesa far from the slightest light pollution, the air glow was able to illuminate the ground enough for me to walk without needing a light. The kicker is that we are so accustomed to artificial light, either through light pollution of the cities, house lights, electronic equipment or dash/headlights from our cars it takes a couple of hours for eyes to adjust to that level of darkness, it is best to be at these dark locations from evening and allow our eyes to gradually adjust to the darkening skies naturally to enjoy the benefit of seeing the night like we were intended. I am by no means recommending going on a hike at night or a stroll through the woods at night without the proper illumination, so don’t even think of doing such, but the next time you have an opportunity to spend a night in a truly dark location do it, put up your tent and pull out your camp chair and sit back watching the stars move across the sky, your eyes will clearly make out the dust lanes in our view of the Milky Way
to view all of these photos at their uploaded size just right click on your mouse and click on “view image”. All above photos were taken about 15 miles north of the tiny town of DeBeque in western Colorado, you still get a slight glow of the city of Grand Junction in each of these images, but the overall sky is rated a Bortle Class 2. Vega State Park, images will be posted in an upcoming blog post, is about 40 miles south of that same tiny town of DeBeque. Again with each photo above Mars and Saturn are also visible to the right of the core of our Milky Way.
So how many of you live in a region that gives you an opportunity to see truly dark skies? How many of you are on the US east coast or Europe? Wanting to experience these amazing dark skies? I am considering doing photo tours and perhaps some workshops coming up in the future if anyone is interested.
