The starfield in eastern Cassiopeia containing an abundance of open star clusters. The most prominent is NGC 663, aka the Letter S Cluster, at bottom. Above it is NGC 654; to its right is NGC 659. At centre is Messier 103. At far right is NGC 457, the ET or Owl Cluster. Above it is NGC 463. The star at far left is Epsilon Cass; the star at right of centre is Delta Cas, aka Ruchba. The 7.5 x 5° field is close to a binocular field of view. This is a stack of 15 x 4-minute exposures with the SharpStar 61mm apo refractor at f/4.5 and with the Canon R6 at ISO 800. Taken from home Oct. 1, 2021. Diffraction spikes added with Astronomy Tools actions.
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.
