Gone to See Hawaii, Maui Day 3: Haleakala National Park.

I left the meeting early to get to the Pu’U’Ula’Ula peak in Haleakala National Park for sunset. When I got to the parking lot I saw this bird, which I later identified as a Chukar. The elevation is about 10,000 feet, and as the sun went down it got windy and cold fast. The thermometer on my GPS indicated 30°F, and I only had a light windbreaker. I didn’t think to carry cold weather gear for the trip to Hawaii. I did get several great images of the sunset over the nearby Haleakala Air Force Satellite tracking station and observatories.

Gone to See Hawaii, Maui Day 1: Haleakala National Park.

While attending a scientific meeting in Hawaii, I had the afternoons free. For the first day I decided to drive to Haleakala National Park to check out a good location for a sunrise or sunset photo shoot on top of the volcano for later in the week. It is amazing going from sea level to Pu’U’Ula’Ula (Red Hill) the summit of Haleakala at 10,023 feet. There were not many bicycles riding up, but many riding down. It looks like the tour operations bring you up the mountain and then let you ride a bicycle down. Up at the summit, I got some images of the rare Haleakala Silversword plant (one in bloom), and the Haleakala US Air Force Satellite Observatory Station. Going down the mountain, I stopped at the Kalahaku Overlook to take a panorama of the volcano crater. Further down, near the visitor center there were a pair of Nēnē (Hawaiian Goose) at the side of the road. The Nēnē is the state bird of Hawaii. I had previously seen Nēnē on the Big Island of Hawaii during a photography workshop with Thom Hogan.

Late Autumn Night Sky Over New Jersey: Star Trails and Time-lapse Video.

Images of star and jet trails plus a time-lapsed video looking south from my house in New Jersey. This was a couple of days before the Geminid meteor shower was supposed to peak, but I did catch a few meteors during the night. A series of images were taken with a Nikon D3x and 24 mm f/3.5 PC-E lens (ISO 400, f/4, 30 sec). The star trail images are composites of 120 images combined with the Startrails program. A time-lapsed video of the entire set was also created using Adobe Photoshop CS5 export to video. When you see Orion, tell me what I did wrong…

Backyard Autumn Night Sky in New Jersey.

Orion, Taurus, Pleiades and clouds. Looking South from my backyard. One of ~ 1000 images taken with a Nikon D3x and 24 mm f/3.5 PC-E lens (ISO 400, 24 mm, f/4, 30 sec). I transformed the series into a time-lapse video using Photoshop (720p, 24p).

Backyard Winter Night Sky Over New Jersey: Time-lapse Video

The ClearSky folks didn’t have a good forecast for the whole night, but I still recorded the night sky looking south. You can see the clouds kept passing over, so no star trails.
