This is NGC 457, the ET or Owl Cluster in Cassiopeia, in a stack of images showing the total number of satellite trails recorded over the 36 minutes of total expposure time this night. By coincidence, the trails frame the main subject, but the number of satellites now above us make it nearly impossible to take a long exposure image, certainly at the start or end of a night, without recording at least one satellite trail, if not more, per image. Some of the parallel streaks could be Starlink satellites. This was from 51懜 north on a mid-October night, between 8:18 pm and 8:52 pm MDT. .
