Views of the sun, moon, and stars
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.
It is hard to believe that it is December. I have not posted anything since Thanksgiving. A lot of end of year activities at work, still more to clean up in the yard after the early snow storm, and finally getting caught up with the Drobo external data drive recovery and new Drobo backup. I have a few images taken with the new Nikon 1 V1 camera that I need to go back and post, along with some pros and cons about the new camera.
The sky was clear, so I put two cameras out early this morning after the moon went down for night sky images. These images were used to put together the following time-lapse video.
Repeat from last night, but at ISO 400. Nikon 1 V1 camera with the 10 mm f/2.8 lens, and the following settings: ISO 400, manual exposure, 30 second exposure, f/2.8, focus infinity (Long exposure NR = off). I used the interval timer, but found that I needed to set the interval to 40 seconds because it takes ~10 seconds to transfer the image from the buffer to the memory card. This is unfortunate, since it leaves a gap if I tried to create stacked star trails (using the Star Trails program). I did manage to catch a few images of meteor trails. The meteor trails were distinct from the many jet trails. The first two were a pair, but faint, the third is caught in two images with the missing section due to the ~10 second delay between images. The late night and early morning images were combined to make a Night Sky time-lapse video.
I wanted to see how the new Nikon 1 V1 camera performs doing night sky photography. I set up the camera with the 10 mm f/2.8 lens, and the following settings: ISO 100, manual exposure, 30 second exposure, f/2.8, focus infinity (Long exposure NR = off). I used the interval timer, but found that I needed to set the interval to 40 seconds because it takes ~10 seconds to transfer the image from the buffer to the memory card. This is unfortunate, since it would leave a gap if I tried to create stacked star trails (using the Star Trails program). I did manage to catch an image of a meteor trail early (5:28 AM) in the morning. The late night and early morning images were combined to make a Night Sky time-lapse video.
