I made 1,000 or so 20 second exposures last night: Rokinon 14mm f/2.8 ISO 6400, Lightroom for dehaze and noise reduction, Starstax for the composite. Go ahead – order a print – you know you want to!
Beautiful early morning flight by Pueblo Balloon
Manual focus (prefocus before it gets dark, tape it down), Canon 17-40 on tripod, f/5.6 or so, ISO 400, Bulb mode (shutter stays open as long as you press the shutter). These are 2,3 ,4, or 5 second exposures, trying to capture only one, interesting burst. These are the 15 prettiest, out of 150 frames. Lightroom to adjust exposure, and crop. Prints here.
