Lighthouses and Night Light at Apostle Islands National Lakeshore

Milky Way over Apostle Islands

We recently told you about a series of posters being produced to promote the dark, starry skies over national parks. As this photo shows, there are some unexpected parks that offer dazzling views of the night skies. This print was produced for Friends of Apostle Islands National Lakeshore as a fund-raiser. Here's the story behind the photo:

This picture was taken early in the morning on June 25th, 2009, of the Outer Island Light Station. A four-minute exposure, this shot was made possible by mounting the camera (a Canon 30D) on top of a telescope with a slow-motion drive, making it possible to cancel the motion of the Earth's rotation. This process allows the camera to capture an incredibly sharp and saturated image of one of the most delightful views of the heavens. A separate four-minute exposure was taken with the telescope drive turned off to capture the Light Station and house.

Conditions must be perfect to achieve such a photograph: crystal clear skies, low humidity, new moon and no airplanes or satellites spoiling the shot. It can only be taken during the summer months when the Milky Way's brightest region is poised above the southern horizon.

The proceeds from the sale of this limited edition print go to the Friends of Apostle Islands National Lakeshore, whose mission is to promote an appreciation for and preservation of the natural environment and cultural heritage of the Apostle Islands National Lakeshore:

A framed, 26-inch by 21-inch copy of this print can be yours for $530, shipping included. For more information, check out this page.

Very cool, Kurt. I didn't know you were a member of the Friends of the Apostle Islands! Or at least get their newsletter!

Mark and John and Ian did an incredible job with this logistically-challenging photo and have done an even more remarkable job raising funds for the Friends with it. We're hoping they can make it into a series, with an amazing night sky or Milky Way photo at each of the park's 8 lighthouses, perhaps one per year.

Print #1 was purchased by Congressman Dave Obey and presented as a gift to Secretary of the Interior Ken Salazar when they both visited the park in August 2009. That print now hangs in the Secretary's suite in the Department of the Interior.

I am very happy to see the value of a dark and starry night promoted by the NPS and the Friends at Apostle Islands. Units of the national park system located away from urban lights offer the public an outstanding opportunity to experience a near pristine night sky. This specific photo reveals more stars than visibile to the naked eye, possibly more than can be observed using binoculars or a small telescope.

Owen, you're the expert, so maybe you can tell me. Aren't most/all of those really distant, very faint objects you've mentioned galaxies, nebulas, supernovas, and that sort of thing rather than individual stars?

Reply @Bob Janiskee:

The photo features the Milky Way, what most of us know as the faint band of light that stretches across the sky during the summer or winter months. The milky way is our home galaxy. The faint light is the light of very distant - and numerous - stars making up the nearer spiral arm of our galaxy. The individual stars are too far away and too faint to be individually visible, but their combined light glows as the path of the milky way. There are, certainly, nebula and star clusters in that band too, but the majority of the light is simple starlight, from the stars in our own galaxy.

Bob, you had me at "series." See you at Sand Island next summer!

Thanks for the explanation, John. So much to little time....

John, I look forward to helping make it happen! Owen, maybe you should come out, too, and see the night sky from this part of the world. Kurt and Bob, you guys could come and do play-by-play.
