While taking the trash out, I noticed that the moon was nearly full. Actually one day after the full moon. Since the sky was clear, I also set cameras up to do some star trails. There definitely are more jets flying than one and two years ago. Also a couple of meteor trails. A couple of notes using the Leica Q2 monochrome for composite star trail images. The ISO needs to be 100 and the exposure time no greater than 4 seconds, otherwise a second dark (shutter closed) image is taken and subtracted to remove sensor noise. Also, I wish the camera had an option to connect an external power source so I could take longer sequences.

Wintertime Backyard Nature in New Jersey.

The folks from Hamlet Tree service started removing dead and diseased trees from the yard. The first stage of the project is to make room for some of the deer fence. Later to clear an area for more wildflowers and a fruit tree orchard. Hope to do some time-lapse videos of their work in the future.
