First Attempt to Capture Starlink Pass Overhead

Bit of a failure. Looking in wrong direction, not wide enough view, too much cloud... ?

There was supposed to be, and I’m sure there was, a pass by of several of the Starlink satelite arrays at about 23:11 last night:

I set my camera to take a load of exposures (details below), pointing roughly toward the southern skies. Unfortunatly, and it could have been for any number of reasons, I don’t think I managed to capture a single one of the satelites. There wassome intermitant clound coverage, or I could have just been aiming too low / too high. I’ve not worked it out yet. I wasn’t able to see any by eye either, so maybe just poor viewing conditions.

Anyway, this is what I got:

  • Camera = Canon EOS 7D
  • Lens = Canon EF 17-40mm f/4L USM
  • Focal Length = 19mm
  • Aperture = f/4.5
  • Individual Exposure time = 14s
  • Interval Between Exposures = 3s
  • ISO = 640
  • No. Exposures ~ 200
  • Total Exposure ~59.7 minutes

Still haven’t worked out a way to automate the image compositing in Gimp yet. I’m sure will when it becomes too painful a task to keep doing one image at a time.
