  • There is a lot happening at the local pond at 2AM. This image shows the stars apparent movement in 45 minutes time. The aurora glowed to the north in hues of red and green. Meteors burned up in the atmosphere. Satellites and airplanes  flew past. It was far from quiet with flapping waterfowl, croaking frogs, and a splashing beaver. Startrail reflections are like mini seismographs, recording ripples in the water. With no wind, all the disturbances are from the beaver splashing.

  • Stars rise over Salt Creek in Weldon Springs State Park. This startrail sequence covers shows the stars movement in 73 minutes. <br />

    Weldon Springs Startrails
  • Stars appear to rotate above this abandoned barn in 3 hours time. In reality it is the stars that are stationary and the earth that is rotating. In 23 hours and 56 minutes, the stars make one counterclockwise rotation of 360 degrees. This 4 minute difference is what causes the stars to change position from night to night, and the constellations to change from season to season. Earth's northern axis happens to be pointed at Polaris, or the North Star. It hardly moves at all in the course of a night. For thousands of years people have been using Polaris to navigate. It not only tells you which way is north, but it also tells you your latitude. In this case the North Star was 40 degrees above the horizon. Those in the southern hemisphere do not have such a star to guide them.<br />
I found this old barn in Jim Edgar State Park a couple nights ago.

  • I combined some of the last aurora images I took before dawn into this startrail. I stacked the pictures in Starstax using comet mode and in reverse order so the stars seem to be rotating clockwise instead of counterclockwise. This allowed the bright purple pillar to show through more easily.

  • The milky way sets in the west shortly after sunset. This was taken from the top of a hill prairie in Jim Edgar State Park. It was a great place to watch a meteor shower.

  • The stars apparent motion is captured behind the Skyline Arch in Arches National Park. A flashlight was used to illuminate the arch from below.<br />

  • This image shows the stars apparent motion caused by the rotation of the earth. I setup my camera point at my tent while I camped in Anza Borrego.

  • While the aurora was out, the International Space Station passed by to the north. The station orbits 250 miles above the earth at 17,000 MPH and circles the earth every 90 minutes.

  • This night was a rare one. The weather was completely clear with no winds, the moon had set, and the temperature was even in the positives. Conditions were perfect for stargazing, and I had to take advantage of it. The dead silence in these grassy hills outside of Buffalo was only interrupted by the occasional howl of a coyote. I pointed my camera north and took pictures for 90 minutes, which I combined into this star trail image. It shows the stars apparent motion caused by the Earth's rotation. Each star in the northern sky takes 24 hours (23:56 to be precise) to make a complete revolution in a counterclockwise direction. The height of the North Star (also known as Polaris) is always equal to the latitude - 44° in this case. Any star less than 44° away from Polaris is circumpolar, which means it never goes below the horizon. The red at the bottom of the picture was a very dim appearance of the aurora. I couldn't see it with my eyes.
    Revolutions
  • After a 35-minute ride on a chairlift in the dark, I arrived at the Aurora Sky Station, 1000 meters above sea level near the top of the mountain Nuolja. Below stretched out a panoramic view of the lake Torneträsk, the lights from Abisko village, and other peaks of the Scandinavian Mountains. The weather was ideal. Even though temperatures were at the lower limit in which the lift is allowed to operate, the skies were clear and the wind was calm. Unfortunately the aurora was calm as well. The northern lights danced a little on the ride up, then faded to a weak glow barely perceptible for the rest of the night. But I tried to make the most of my time up here by shooting this startrail image. I processed it in a way to fade the trails into the background while bringing out the colors of the faint green aurora band. Even though my camera was pointed due north, it was not possible to include the North Star in the shot, at least not without shooting vertically. In Arctic latitudes the North Celestial Pole is too high up in the sky.

  • While camping at Castle Gardens, I captured the stars for 2 hours to put together into this startrail image. A campfire cast a warm glow on the bluffs and hoodoos above.
