Autumn Dawn in New Jersey.

While taking the trash out early in the morning, I noticed the Crescent Moon and Venus shining brightly in the eastern dawn sky.

Early Autumn Night Sky Over New Jersey.

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.

Last Summertime Night Sky Over New Jersey.

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. Star Trail composite image created with the jpg “out-of-the-camera” image files using PhotoShop CC (scripts, statistics, maximum).

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.
