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.

Day 2 of the Bok Choi seeds sprouting time-lapse videos. First video, images taken every 1 minute for 13 hours 36 minutes then displayed at 12 frames/second. The second video images taken every 1 minute for 5 hours, then displayed at 12 frames/second.

Daily Electric Energy Used (95.7 kWh) from Sense. Daily Solar Electric Energy Produced (22.7 kWh) from Sense and SolSystems. Some sun and a bit warmer outside so the resistance heaters were not needed, but the Geothermal HVAC system was on most of the day. Deficit of 73.0 kWh.

Autumn Day Nature and Working Outside and in the Garage in New Jersey.

Full moon before the lunar eclipse. Unfortunately, a rain storm came through while the eclipse took place.

My Little Planet time-lapse videos for the day. 1) Red Rover. Moving items, switching from the front loader to forks, adding additional support to the pallets being used to support the tractor implements. 2) Tent Box. Starting to install the inner cold weather lining in the tent box. It got dark before I could finish.

Backyard Springtime Night Sky Over New Jersey.

One day past the Full Moon. Comparison images taken with a Nikon D850 camera and 80-400 mm VRII lens with and without a 2.0x TC-EIII teleconverter. Both images zoomed to project as the same size. To my eye, the one without the teleconverter is sharper.

Seven-Years Ago (01-September-2012) — Celtic Sea

Gone to see Europe. Semester at Sea. Fall 2012 Semester Voyage on the MV Explorer. Day 10: At Sea, North Atlantic Ocean, Celtic Sea, and Irish Sea.

There were several Northern Gannets following the MV Explorer. I wanted to get an image of one crossing the full moon. I took lots of pictures, but only came close a few times. Then there was the issue of whether the moon, or the bird should be in focus.

Summer Nighttime Sky Over New Jersey.

Composite of nearly full moon images. Rather than an in-camera composite image (as I have done in the past), these were created during post processing (Photoshop CC Pro, statistics, maximum). I set a Nikon D5 camera up with a 600 mm f/4 VR telephoto lens to take images every 1 second. I was hoping to catch a jet pass in front of the moon, as I had seen the previous night — but no joy. When I get some time I will make a time-lapse video of the moon crossing the screen.
