Summer Nighttime Sky Over New Jersey.

The waning gibbous moon was bright, so I took images with several different cameras and lens. All of the shots were done hand-held using lens or sensor image stabilization. Images were processed with Capture One Pro and then cropped so the size of the moon would be the same.

Summer Nighttime Sky Over New Jersey.

This was the second night in a row with a clear sky. The moon would rise a hour later. I decided to do star trails again with the Ricoh Theta Z1 360 degree camera. Camera settings (ISO 400, dual 2.6 mm fisheye lens, f/2.1, 60 sec). The images were processed with PTGUI, Capture One Pro, and Photoshop CC to create the following 360 degree Equirectangular Panorama, 360 degree Little Planet View, and 360 degree Tunnel View images. If you look close, you can see some firefly trails.

Summer Nighttime Sky Over New Jersey.

With a clear night sky, I decided to try the new Ricoh Theta Z1 360 degree camera to create some star trails. I set the camera up on my back patio (ISO 400, dual 2.6 mm fisheye lens, f/3.5, 60 sec). The camera can collect 358 raw (DNG) images which corresponds to just under 5 hours at 60 second exposures. The images were processed with PTGUI, Capture One Pro, and Photoshop CC to create the following 360 degree Equirectangular Panorama, 360 degree Little Planet View, and 360 degree Tunnel View images. I’ve also included a time-lapse video of the night sky

Summertime Backyard Nature in New Jersey.

I spent the morning working on the patio (time-lapse little planet video). The Grow Towers are doing well. I’ve been harvesting large radishes, broccoli rabe, Swiss chard, and dill. Zinnia and Coreopsis are blooming in the outer cloth pots. I planted Marigold and Roselle (Hibiscus sabdariffa) in the inner set of cloth pots. No Marigold flowers yet, and five of the Roselle are growing fast. Several volunteer tomatillo and/or ground cherry plants also sprouted in the inner set of cloth pots.

A herd of deer passed through the backyard just before it started to rain. Then before the sun went down I noticed a partial double rainbow.

Early Summertime Backyard Nature in New Jersey.

The late afternoon and early evening thunderstorms passed north and south of here. Image of the first quarter moon with the storm clouds to the south a little before sunset.

Birds of the Day: Blue Jay, Gray Catbird, Northern Cardinal, Tufted Titmouse, House Finch, and Red-bellied Woodpecker. I didn’t know that the woodpeckers like fruit. When this woodpecker visited all of the other birds, including the Blue Jays left it have the birdfeeder to itself.
