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 constellation portrait of Cassiopeia (right, as the W of stars) and Perseus (left). Included are several of the bright pink emission nebulas in this part of the Milky Way, notably the Heart and Soul Nebulas at top and the California Nebula at lower left. At bottom right is the Andromeda Galaxy. The Double Cluster in Perseus is at centre. At bottom is the large open star cluster NGC 752, while above it is M34. Capella is at far left; Mirphak is at centre in the middle of the Perseus OB Association of hot young stars. This is a stack of 5 x 4-minute exposures with the 28-70mm Canon RF lens at f/2.8 and 35mm, on the Canon Ra, shooting through an URTH Night broadband light pollution filter. A final exposure through an Alyn Wallace/Kase StarGlow filter added the glows on stars. Frost on the lens this night spoiled the last few frames and were not used. The camera was on the Star Adventurer Mini tracker.
