A 120° panorama of the dawn sky on July 16, 2017 with the northeast horizon (left) colourful with dawn twilight, Venus in the east (centre) near Aldebaran, and the waning Last Quarter Moon in the southeast (at right). This serves to demonstrate the 90° angle between the waning quarter Moon and the sunrise point (and the Sun). And also the twiight colours on a very clear morning. The sky is also much darker toward the Moon at the 90° point due to natural sky polarization. This is a 5-section panorama with the 14mm Rokinon lens and Canon 6D, stitched with PTGui. ACR would not stitch this.
A 360° panorama captures the arch of the Milky Way on a June night, over Two Jack Lake, near Banff, Alberta. Mount Rundle is at centre, and Cascade Mountain behind the trees at right. Mars (brightest) and Saturn shine above Mt Rundle. Lights from campers on the lakeshore are at left while light pollution from Banff and Calgary light the scattered clouds. The Milky Way stretches from Perseus at far left in the northeast to Sagittarius at centre in the south. The northern sky at far left and right is blue with lingering summer twilight that lights the northern sky all night near summer solstice. This is a stitch of 28 segments in 4 tiers of 7 segments each with the iPano motorized panning unit. Each was 20 seconds at f/2.8 with the Sigma 24mm lens and Nikon D750 at ISO 5000. The scene can be cropped off at right to frame just the lake and Milky Way.
Taken from Arizona, Masai Point, Chiracahua National Monument, in May 1995. Taken with Plaubel Makina 6x7 camera on 120-format Fujichrome Velvia 50 slide film. Shows classic normal colors of twilight from orange thru to deep blue. Scanned at 16 bits per channel but converted to 8 bits.
