Coma Berenices & Virgo with Arrows (85mm EOS Ra).jpg

Add to Cart Add to Lightbox Download
This is a wide sweep from Coma Berenices down to Virgo covering the main "realm of the galaxies" region of the Coma-Virgo supercluster of galaxies covering some 25° of sky from north (at top) to south. At this scale even the largest and brightest galaxies show up only as small smudges, but the field is filled with them! At top right is the open star cluster Mel 111, the Coma Berenices star cluster. The bright star at bottom left is Vindemiatrix, or Epsilon Virginis. The field contains the heart of the Coma-Virgo galaxy cluster, the Markarian's Chain at lower right.

This is a stack of 25 x 2-minute exposures with the Canon EOS Ra at ISO 1600 and the Samyang 85mm AF lens, on the Sky-Watcher Star Adventurer 2i tracker. Out of 30 frames taken about 5 were trailed enough to warrant deleting from the stack. Taken from home on a very clear night, April 13, 2021. Stacked and aligned in Photoshop, using Median stack mode to eliminate satellite trails, which were sadly present in almost every frame. No darks or LENR applied.
