The Interstellar Dust Clouds of Taurus and Perseus
California to Pleiades (85mm EOS Ra).jpg
A wide-field image of the region of Perseus and Taurus from the pink California Nebula (NGC 1499) at top, to the blue Pleiades star cluster (M45) at bottom. In between and surrounding the main bright objects are many tendrils of interstellar dust clouds, varying in shades of brown and pale blue.
Around the Pleiades the faint clouds reflect some of the lblue light of the young stars, but away from the Pleiades the clouds take on a warm reddish tone, or appear as just dark fingers blocking all light from behind. At centre right are some brighter patches known as IC 348 around the star Atik, aka Omicron Persei. The glow at left in the darkest cloud is IC 2087. The small star cluster at upper right is NGC 1342.
This is a stack of 30 x 4-minute exposures with the Canon EOS Ra camera at ISO 800, and the low-cost Rokinon 85mm f/1.4 lens at f/4 and shooting through a NISI Natural Night light pollution filter, a mild broadband filter. The lens, despite being stopped down, is still subject to some chromatic aberration, which lens corrections help with but cannot fully eliminate at the raw development stage.
All stacking, alignment and processing with Photoshiop 2021, with luminosity masks created with Lumenzia v9 extension panel , which was very helpful in bringing the faint dust clouds out from the dark background. No dark frames or LENR applied on this cool winter night.
