A 360° panorama of the upper field of the Texas Star Party at the Prde Ranch near Fort Davis, TX, May 13, 2015, taken in deep twilight. The panorama shows the field of telescopes and observers getting ready for the night of deep-sky viewing and imaging. Venus is the bright object at right of centre and Jupiter is above it. The Zodiacal Light stretches up from the horizon and continues left across the sky in the Zodiacal Band to brighten in the east (left of centre) as the Gegeneschein. I shot this with a 14mm lens, oriented vertically, with each segment 40 seconds at f/2.8 and with the Canon 5D MkII at ISO 3200. The panorama is made of 8 segements at 45° spacings. The segments were stitched with PTGui software.
