Backyard Winter Night Sky in New Jersey: Star Trails and Quadranitids Meteors.

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.

Backyard Winter Night Sky over New Jersey: Moon in Conjunction with Jupiter.

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).

Backyard Autumn Night Sky in New Jersey: Time-lapse Video and Star Trails.

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.

Late Autumn Night Sky over New Jersey: Star Trails and Meteor Trails.

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.

Late Autumn Night Sky over New Jersey: Meteor Trails and 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.
