Backyard Nighttime Sky Over New Jersey.

The sky cleared just long enough before dawn to capture images of Comet C/2022 E3 (ZTF). This time just with the Vespera telescope. The comet is high enough above the horizon to the north-east before dawn to be viewed above my house from my patio. I use the Sky Live website to get the location of the comet, and then enter the numbers into the Singularity application. Within minutes, both the Vespera had the comet centered and start taking images.

Summer Nighttime Sky Over New Jersey.

This was the third 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. This time I mounted the camera horizontally so one of the fisheye lenses pointed straight up. I wanted to see if this would make a difference with the star trails. 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. Interestingly, the camera adjusted the output with a correct horizon. It turned out that the horizontal settings were not as stable (wind jitter?). Fortunately, the PhotoShop CC settings I use to create the composite images (scripts, statistics, maximum) has a setting that tries to align images. Presumably using major common features in all of the 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

Backyard Spring Nighttime Nature in New Jersey.

Even more fireflies than last night. It was a bit warmer out. The activity didn’t drop off until after midnight when the temperature went below 60°F. Composite of images taken with a Nikon D4 camera and 200 mm f/2 VR lens (ISO 800, 200 mm, f/8, 30 sec).
