Fourth consecutive night with dark (relative — this is New Jersey) clear skies. This time Night Sky Star Trails with a Nikon D850 camera with a 10.5 mm f/2.8 DX fisheye lens (ISO 100, 10.5 mm, f/2.8, 30 sec). Note a full frame camera with a DX sensor lens, thus some of the sensor is not used. Star Trail composite image created with the jpg “out-of-the-camera” image files using PhotoShop CC (scripts, statistics, maximum). A lot fewer jet trails than in previous years. Clouds started coming in during the early morning hours.

Autumn is coming. Getting colder outside allowing me to open the windows and turn off the Geothermal HVAC system. Third consecutive night with dark (relative — this is New Jersey) clear skies. Repeat Night Sky Star Trails with a Leica SL2 camera with 16-35 mm lens (ISO 200, 16 mm, f/4, 60 sec). This time portrait mode. Same number of images (152) as last night before the batteries failed. Do wish there was a way to provide external power to the camera for longer overnight sessions.

Daily Electric Energy Used (40.1 kWh) from Sense. Daily Solar Electric Energy Produced (53.3 kWh) from Sense and SolSystems. Sunny with a few clouds. Geothermal HVAC system off. A surplus of 13.2 kWh. Stove left on boiling water for tea… Or an expensive way to humidify the house.
Taking advantage of several nights with clear skies. For comparison to the Star Trail images yesterday, I set up two high-resolution full-frame cameras to capture the night sky from my patio. 1) Leica SL2 camera with 16-36 mm lens (ISO 200, 16 mm, f/4, 60 sec). 2) Nikon D810a with 8-15 mm fisheye lens (ISO 200, 11 mm, f/4, 120 sec). The Leica (2 batteries) captured 152 images before running out of power. The outdoor temperature dropped to 36° F. Then Nikon camera (2 batteries) captured 174 images before taking the camera back inside (could have gone on longer). The first two Star Trail composite images were created with the jpg “out-of-the-camera” image files using PhotoShop CC (scripts, statistics, maximum). The second two Star Trail composite images were created with the DNG or RAW image files processed with Capture One Pro and then using PhotoShop CC (scripts, statistics, maximum).

Ricoh Theta Z1 camera set up to capture the night sky from my patio. Two versions of the 360 Equirectangular, 360 Little Planet, and 360 Tunnel view. The first ones processed directly with the jpg files from the Theta Z1 camera. For the second set, the DNG files (dual fisheye) were first processed with Capture One Pro then converted to single 360 Equirectangular 16-bit TIF files. By processing and converting the DNG files to 16-bit TIF files I was able to bring more detail out of the dark shadow areas in the images.

Out working on the patio, I harvested the Broccoli Rabe and Radishes in the Grow Towers. This opened up light for the Basil and Pepper plants. I also distributed worms in to the composting tubes in each Grow Tower. I used the Ricoh Theta Z1 360 degree camera to make time-lapse Little Planet videos of the work on the patio. Same workflow as yesterday: Theta Z1 Camera set to record images using program auto mode (shutter, aperture, white-balance, JPG + RAW (DNG) every 10 seconds. Camera mounted on a tripod just above head level. The camera collected ~ 360 images (~ 1 hour) before running out of internal storage space. The DNG dual fisheye images were processed with Capture One Pro, saved in TIF format. Then converted to 360 degree equirectangular pano images with PTGUI (batch process). The Little Planet time-lapse video was created using PhotoShop CC (image converted to 1:1 format (7430 x 7430), rotated 180 degrees, converted to polar coordinates, then exported as a MP4 video (1920 x 1920, 10p). Rotation to the video was added using Premiere Pro.
