Vertical symmetry

Vertical alignment of the AT1 telescope and the Magellanic Clouds at Paranal Observatory. The bright compact source above the Small Magellanic Cloud is the globular cluster NGC104. You can also see some really faint red and green airglow towards the horizon.

 

The Magellanic Clouds are two dwarf galaxies in orbit around the Milky Way, located at at distance of 160,000 light years (large one) and 200,000 light years (small one). When the light that we now receive from the Magellanic Clouds left those galaxies, the first Homo Sapiens had just appeared on Earth. And these are some of the closest galaxies to us! This gives you an idea of how ridiculously large the universe is.

 

I took this image with a Canon 6D and a Tamron 45mm lens at f/1.8. I can’t praise this Tamron lens enough. It’s incredibly sharp from corner to corner!

 

This is a stack of 11 untracked images of 10 seconds each, at ISO6400. Given the rotation of the sky, I stacked the foreground and background separately. The stacking was done in Hugin, with further editing in Affinity Photo.
