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.
The bright Cygnus Starcloud (at right) and collection of red emission nebulas in central Cygnus, including the North America Nebula (NGC 7000) at left near the bright star Deneb. The dark Northern Coalsack is to the right of the North America Nebula. The IC 1318 emission nebula complex is at centre. The star cluster NGC 6819, aka The Foxhead, is at far right. The cluster NGC 6866, aka The Kite, is to the left of 6819. At top right is the cluster NGC 6811. This is a stack of 4 x 2-minute exposures at f/2.8 with the Rokinon 85mm RF lens on the Canon EOS Ra camera at ISO 1600, and through the Kase Neutral Night broadband filter, with an additional exposure layered in taken through a Kase/Alyn Wallace StarGlow filter for the glows. Taken from the Alberta Star Party site on September 3, 2021, with the camera on the Star Adventurer Mini tracker. Stacked, aligned and blended in Photoshop. Luminosity mask adjustments applied with Lumenzia and Zone System Express v7.
