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.

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.

Backyard Autumn Nighttime Sky Over New Jersey: Leonid Meteors.

I had two cameras out monitoring the night sky with the hope of catching a Leonid Meteor. Two of the images had small meteor trails. A bit later there was something much brighter. I am not sure if it is a meteor, however it does not have parallel lights or regular strobe flashes like a jet trail. The other possibility would be a satellite trail. The curved trail is due to the fisheye lens. I used DxO to process the image to correct for the fisheye effect (4th/final image).

Backyard Summertime Night Sky Over New Jersey.

Perseid Meteor Shower. Conditions for viewing the Perseid Meteors this year were not good. The moon was full with relatively high humidity and some clouds. I set two cameras up to take images overnight, and got maybe three images of meteors. I’ve made a time-lapse movie from the two image sets.

As a side note, I am running out of hard disk space. I could get another WD My Book external drive, but have run out of USB and Firewire ports on my computer. I’m thinking about a Dobro disk array. What ever I do, I also need to maintain an off-site backup copy. I worry about some of the cloud options, both due to cost and the fact that ATT limits me to 5 GB/month of broadband internet access.
