Twilight

Please share if you enjoy starry nights!

We recently returned from an amazing 7 day backpacking trip through the Eagle Cap Wilderness. Believe it or not, this is how we like to spend our vacation time. Hiking countless miles in high elevations gives us time to enjoy each other in deep conversation, admire the blooming wildflowers, and witness clear, dark skies from our tent perched high on mountain tops. We did however, return with a few battle scars from blood thirsty mosquitos, intense sunshine, and blistering feet. In addition, we were starving for fresh produce (and a big fat cheeseburger) from eating only freeze-dried food for a week. Why do we do it you may ask? Because immersing ourselves in pristine nature heals our souls. No noise pollution, TV, cell phones, emails, or deadlines gave us plenty of time to just enjoy every moment to moment as each beautiful landscape unfolded or animal entertained us. Each natural gift revived us and reminded us why we love to disappear in the wilderness.

I heard Eagle Cap had some of the darkest skies in Oregon, but of course, I just had to see for myself. After a few all-nighters, all I can say is WOW! The night sky was so intensely clear and dark; it had to be a ‘Class 2’ on the ‘The Bortle Dark-Sky Scale’ (Visit http://bit.ly/1eCr7pd for more info on the Bortle Scale). The darkness was so deep; it was difficult capturing the vastness and beauty of the high altitude landscape. So instead of shooting during the middle of the night, I concentrated on shooting during what’s called the ‘Nautical Twilight’. Nautical Twilight is the time when the center of the sun is 12 degrees below the horizon, and only general or vague outlines of horizon are visible. Personally, I like to call it ‘Blue Hour’. This time period provided just enough light to capture most of the visual elements of the landscape.

This image was taken at Moccasin Lake and includes Eagle Cap Peak which towers at 9595 feet in altitude.

Lots more to come!

Mr Bortle thank you for your scale "To help observers judge the true darkness of a site, I have created a nine-level scale. It is based on nearly 50 years of observing experience. I hope it will prove both enlightening and useful to observers — though it may stun or even horrify some! Should it come into wide use, it would provide a consistent standard for comparing observations. Researchers would also be better able to assess the plausibility of an unusual or marginal observation. All around, it could be a boon to those of us who regularly scan the heavens." - See more at: http://www.skyandtelescope.com/astronomy-resources/the-bortle-dark-sky-scale/1/?c=y#sthash.RgI8cD7c.dpuf

Manufacturing lights that focus on controlling excess glare and spill will help decrease light pollution in cities.

If you are using the Loss of the Night app for your Android phone you'll want to check out the blog on this citizen science program to measure light pollution:

A national park the size of Switzerland became the largest The Royal Astronomical Society of Canada Dark Sky Preserve in the world! We're hoping to also see them apply for IDA designation www.darksky.org/reserves

+Ben Canales has developed an amazing new VIDEO! of the night sky. That's right, it's not a timelapse, it's actual video of the night. Enjoy! This is new and exciting technology!

To preserve and protect the nighttime environment and our heritage of dark skies through environmentally responsible outdoor lighting.
Introduction

IDA is the recognized authority on light pollution. Founded in 1988, IDA is the first organization to call attention to the hazards of light pollution, and in 24 years of operation our accomplishments have been tremendous.

We promote one simple idea: light what you need, when you need it. We know some light at night is necessary for safety and recreation. We work with manufacturers, planners, legislators, and citizens to provide energy efficient options that direct the light where you want it to go, not uselessly up into the sky.
