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 portrait of the W-shaped constellation of Cassiopeia, with her various star clusters and emission nebulas, and with the area laced with dark nebula. . For nebulas — At upper left is IC 1805 and IC 1848, the Heart and Soul Nebulas. At upper right is NGC 7822 and Ced 214. At bottom is NGC 281 the Pacman Nebula. Just below centre is the faint IC 59 and IC 63 reflection nebulas near the star Gamma Cassiopeiae. For star clusters — at far left is the Double Cluster NGC 869 and NGC 884. Left of centre is NGC 663. Below centre is NGC 457. At bottom right on the edge of the frame is NGC 7789. I should have framed the scene a bit farther to the south! This is a stack of 11 x 6-minute tracked but unguided exposures at f/2.8 with the Rokinon 85mm lens and Canon EOS Ra at ISO 1600, blended with a single simular exposure through a Kenko Softon A filter to add the star glows. All were also shot through an Astronomik CLS clip-in filter, to reduce sky glow and enhance the nebulas. Taken December 4, 2020 from home on the AP Mach 1 mount.
