Cassiopeia nearly overhead on an autumn night, amid the pines at Athabasca Fall, Jasper National Park, Alberta. The Andromeda Galaxy is at top, Perseus is at upper right, and Cepheus and Cygnus at lower left. This is a stack of 4 exposures for the trees (mean combined to smooth noise) and one for the sky, all 25 seconds at f/2 with the 20mm lens and Nikon D750 at ISO 6400. All exposures untracked. Light cloud added the natural star glows.
Cassiopeia and Cepheus in a stack of 5 x 4 minute exposures with the Canon 5D MkII at ISO 800 and 50mm Sigma lens at f/3.2. Plus two exposures taken thru the Kenko Softon filter for the star glows. Takes in the nebulosity in this part of the Milky Way from IC 1396 (at right) to IC 1805 (at left). Taken from home Sept, 29, 2013.
A mosaic of the region around the centre of the Milky Way in Sagittarius and Scorpius. The field takes in the Milky Way from the Cat's Paw Nebula at bottom edge to the Eagle Nebula at top left. In between from top to bottom are the Swan Nebula (M17), the Small Sagittarius Starcloud (M24), the Trifid and Lagoon Nebulas (M20 and M8) and the open clusters M6 and M7. The prominent dark nebula at right is the large Pipe Nebula (B78) with the small Snake Nebula (B72) above it. The whole complex is visible to the naked eye as the Dark Horse. This is a mosaic of 6 panels, each a stack of 5 x 3 minute exposures with the 135mm lens at f/2.8, and with the filter-modified Canon 5D Mark II at ISO 1600 tracking the sky on the iOptron SkyTracker, with no guidind. Images were stacked and stitched in Photoshop CC. Taken from the Four Bar Cottages near Portal Arizona, May 4/5, 2014.
