Explore Scientific ES127mm apochromatic refractor, Canon 550D, single 450 sec exposure @ ISO400, October 25, 2014.
A recent thread on Cloud Nights asked folks to share examples of satellites/planes and other spurious objects they’ve captured so I dug up this an image of a meteor trail I caught while imaging M42 at the Staunton River Star Party two years ago. Nearly every single one of my subframes had satellites passing through it due to the high density of geostationary satellites “parked” in that direction. The transient object in this subframe was different than the others however because it looked more like a smoke plume rather than a line which is consistent with the ionization trail of a meteor passing through the atmosphere. What a lucky capture!
