Animal Tracks in the Snow

We had a couple of inches of snow yesterday. This morning, I went on a walkabout looking for animal tracks in the snow. I found bird, cat, fox, and rabbit tracks. I was especially interested in finding where the gaps in the deer fence were. In the past some of the larger critters (raccoons and possums) have enlarged these holes to the point where the deer finally got through. In those spots I needed to install a bottom section of plastic-coated wire fence to close the gaps. First a video of where a neighborhood cat gets under the front gate. She has used this as a way to escape being chased by a fox.

Night Sky, Moon, Star Trails, Jet Trails, and Meteor Trails over New Jersey

The night sky started cloud free. I wanted to have the telescopes out but wasn’t really sure how long the sky would remain clear. I set up a Nikon Z9 camera with a 8-15 mm fisheye lens pointed SSE to monitor the sky. Settings for the camera were 15 mm, ISO 800, f/11, and 120 second exposures using the intervalometer with a 4 second delay between exposures. Composites were created using PhotoShop (scripts, statistics, maximum). First image, the sky was relatively clear for the Vespera Pro telescopes to observe the moon. Second image, an 8-minute segment with a meteor trail. Third image, the sky was relatively clear for the Vespera Pro telescopes to observe M42, the Orion nebula. Fourth image, the full night showing lots of clouds passing. I’ve also included a slideshow with 28-minute star trail segments for the night. At the end there is time-lapse video of the night sky.

Contact me if you are interested in a Time-lapse Video of the Morning or Afternoon session at the Birdfeeders. My setup for the birdfeeder images is a Nikon D850 camera and 200 mm f/2 VR lens set to take one image every 5 seconds over a 5 hour period (~3600 images). The new time-lapse video format is 720p (1080 x 720 pixels) and 1 frame/second. The length of the video is about 1 hour in a 1 GB MP4 file. The previous time-lapse videos of the birdfeeders were at 12 frames/second, and to be honest were too fast to identify the birds.
