Satellite Trails in Coma Berenices (April 24, 2022).jpg

This is a stack of images demonstrating the number of satellites passing through the field of a wide-field telescope over a little more an hour. The field frames the Coma Berenices star cluster. This is from my home at 51° North, a latitude more prone to seeing satellites lit by the Sun well into the evening, if not all night closer to summer solstice. Most trails are north-south so they are likely NOT Starlink satellites but polar orbiting satellites. Interesting that the trails have different colours, likely from their solar panels or other structures reflecting blue and gold tints.

This is a stack of 12 x 6-minute exposures started in deep twilight (thus the blue sky background) on April 24, 2022, stacked (with Maximum stack mode) to add the exposures together so the trails accumulate, rather than a median stack mode to eliminate the trails as would normally be done.

This was with the Sharpstar 61 EDPH II refractor at f/4.5 and Canon EOS Ra at ISO 800 for a field of 7.5° x 5°, so similar to binoculars.
