David's Images of the Day Photoblog
Views of the sun, moon, and stars
I used a 16 mm Fisheye lens to take acquire some winter night sky images. The images were combined using the startrails.exe program to get the star trail images. The first image is a composite of 15 60 second images relatively early in the evening. The next three are composites of 16, 35, and 300 second (5 minute) images.
The extended family was on a winter vacation in Norway, traveling north on the Hurtigruten ship M/S Kong Harald. This was day 6 of the voyage traveling north along the Norwegian coast. The stops on this day were in Øksfjord (02:15), Hammerfest (05:15-06:45), Havøysund (09:45) Honningsvåg (11:45-15:15), Kjøllefjord (17:45), Mehamn (20:00), and Verlevåg. During the stop in Honningsvåg we took a bus to North Cape (Nordkapp) traveling through the North Cape Tunnel. Later that night, the Captain announced that Auroras (Northern Lights) were visible.
The sky was clear last night so I set up two cameras to record the night sky. The SpaceWeather site reported that the Quadrantids meteor shower should peak in the early morning hours. The Nikon D3x with a 24 mm f/1.4G lens was set up to look north above my roof. I used an external power supply for this camera so I wouldn’t need to change batteries during the night. The second camera was a Nikon D3 with a 14-24 mm f/2.8 lens looking south. For both cameras, I used the MC-35 remote set for 59 second exposures, once a minute (the extra second is needed to transfer the image from the camera to the memory card). It was cold (getting down to 10° F), and I was glad that at least one camera was using an external power supply. I had to change the battery in the D3 every 2 hours, and even then it was so cold that the battery ran out before the time. The following are a meteor trail image and a time-lapsed video of everything from the night.
Jupiter is in Conjunction with the Moon Tonight. If you get a chance, go out and look. (http://www.spaceweather.com/). Jupiter is the small dot in the bottom right, about 4° from the moon. Image taken with a Nikon D3x and 300 mm f/2.8 lens (ISO 100, 300 mm, f/5.6, 1/100 sec).
I missed the Lunar Eclipse because I am on the east coast. The sky was clear and the moon was full, so I did take some images and DSLR videos with a Nikon D3s and 600 mm f/4 VR lens + TC-E III 20 teleconverter. The D3s is limited to a 5 minute 720p HR video, so I would keep going out and restarting the videos. It was cold, and I wasn’t going to stay out there. The amazing thing when I started viewing the videos, on the very first one saw that I captured a bird flying across the moon. The duration of the transit was about 0.1 second. The frame-grab image from the video shows the bird in front of the moon. I think that it is a sea bird based on the wing shape, but hope that a bird expert can help with the identification. I’ve also included a video of the bird transit. The first pass is real time, the next six repeats are slowed down 10x.
