Cassiopeia (centre), Cepheus (right of centre), and the Andromeda Galaxy (at bottom) in a vertical segment from an attempted panorama along the Milky Way, from New Mexico, December 6, 2013. Perseus and the Double Cluster are at left. This is a stack of 4 x 3 minute exposures with the 35mm lens at f/4 and Canon 5D MkII at ISO 1600, plus a single shot through the Kenko Softon diffusion filter for the star glows.
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.
A framing of some of the main open star clusters in eastern Cassiopeia, including: NGC 663 at lower left and NGC 457 at upper right. NGC 457 is known as the Owl or ET Cluster. Above NGC 457 is smaller NGC 436 and above NGC 663 is smaller NGC 654. To the right of NGC 663 is NGC 659. Between NGC 663 and the bright blue star Ruchbah is Messier 103. The yellowed cluster in the extreme lower left corner is Be 6. This is a stack of 20 x 5-minute exposures with the SharpStar 76mm EDPH with its f/4.5 reducer/flattener, and the Canon R5 at ISO 800, on the Star Adventurer GTi mount, autoguided with the Lacerta MGEN3. No filters were employed.
