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.
