A horizon to past-the-zenith mosaic and panorama of the northern autumn sky and the related Greek mythological constellations: from the watery constellations of Aquarius, Pisces, and Cetus at the bottom near the horizon, up to Pegasus and Aries in mid-frame, on up to Andromeda and Pegasus at upper left, and Cassiopeia and Cepheus at top of frame in the Milky Way overhead. The Andromeda Galaxy is just above centre. Most of these constellations are related in Greek mythology, with Andromeda being the daughter of Cassiopeia and Cepheus, who was rescued from the jaws of Cetus the Sea Monster by Perseus, who rode on Pegasus in some accounts. Zodiacal Light brightens the sky at bottom right in Aquarius, and angles across the frame to the left. I shot this from home on a very clear night January 2, 2016 with the Zodiacal Light plainly visible to the naked eye. This is a mosaic of 5 panels, each a stack of 5 x 2 minute exposures, plus each panel having another stack of 2 x 2 minute exposures blended in, and taken through the Kenko Softon filter to add the fuzzy star glows to make the constellations stand out. All were shot with the 24mm Canon lens at f/2.8 and Canon 5DMkII at ISO 1600. All tracked on the AP Mach One mount. All stacking and stitching in Photoshop CC 2015. Final image size is 8500 x 5500 pixels and 3.6 gigabytes for the layered master.

An Iridium flare, albeit partly obscured by cloud, in a wide-angle shot of the southern sky on an early evening on a December night from southeast Arizona. The Zodiacal Light is prominent across the sky from the southwest to high i the south, despite the thin cloud. Fomalhaut is the bright star right of lower centre, and Diphda the star above the Iridium flare. I shot this December 10 from the Quailway Cottage near Portal, Arizona. This is a stack of 3 2.5-minute tracked exposures to smooth noise plus one more exposure for the Iridium flare itself and that added the ground. All with the 15mm lens at f/2.8 and Canon 6D at ISO 1600.
