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.
Comet C/2022 E3 (ZTF) in the constellation of Auriga on the night of Feb 8, 2023. The comet is the small cyan-coloured glow above centre. It was technically in Auriga but heading south into Taurus and in front of the Taurus Dark Clouds here at centre. Mars is the bright orange object right of centre. At right are the Pleiades and Hyades star clusters, the latter with reddish Aldebaran. Other Messier-catalogue star clusters are in the frame: M36, M37 and M38 in Auriga and M35 in Gemini. The red emission nebulas in this part of the Milky Way also stand out, notably the California Nebula, NGC 1499, at top in Perseus, and the Flaming Star Nebula, IC 405, in Auriga at centre. At bottom is the large faint nebula around Lambda Orionis, or Meissa, in Orion. Capella is at top; Castor and Pollux are at left. This is a stack of 4 x 1-minute exposures at ISO 1600 with the red-sensitive AstroGear modified Canon R and with the RF28-70mm lens at f/2.8 and 28mm. This is one segment of a Milky Way panorama taken this night, from Dinosaur Provincial Park, using the Star Adventurer tracker.
