Unintentional Camera Movement Astrophotography

Most of astrophotography is long exposure photos (except photos of sun and some other exception). During long exposure time a lot of can happen. Tripod may move, focus of camera may change, etc. Sometimes you even not remember what happen and only see some strange result on photo. I started astrophotography in middle school with such weird photos. Photos had UFO, which I did not saw by naked eye. Probably it was reflection of car light but maybe not.

There is very close popular photo technic - Intentional Camera Movement. But I am talking about Unintentional Camera Movement. This is one of the photos from adventures in Bolivia. Photo was done in Salar de Uyuni. Interesting effect – looks like camera reached warp speed. No Idea how it happened, probably changed zoom.

Bolivia Astrophotography - Salar de Uyuni at Night

It's something unreal. Photos were done during a Uyuni stargazing tour. Salar de Uyuni Bolivia Milky Way, Southern hemisphere sky, Crux constellation, red and green Airglow, elevation 3,650 m or 12,000 ft. Salar de Uyuni is the world's largest salt flat. Hexagonal formations on the surface is visible on photos. Such formation is a result of salt crystallization from evaporating water.

With 10,582 km^2, more than 10 billion tons of salt and containing up to 70% of the world’s lithium reserves, Salar de Uyuni is the world’s largest salt flat, a vast salt plain near the crest of the Andes in southwest Bolivia has amazing, fantastic night sky view!

Zodiacal Light Bolivia Astrophotography

Zodiacal light - Bolivia Astrophotography - 2 hours after sunset (elevation: 4020 m / 13190 feet). Jupiter is on the top of the image. Photo was done near Hotel Jardines De Mallku Cueva, Bolivia. New Moon. Canon EOS 60Da, 25 sec., Canon Lens EF16-35mm, f/2.8, ISO 6400, panorama of 3 images. Digital cameras are more capable in collecting light, but even visually the Zodiacal light was clearly visible to the naked eye.

Zodiacal light is a faint, diffuse, and roughly triangular glow that is visible in the good dark night sky far from any light pollution and appears to extend from the Sun's direction and along the zodiac. The zodiacal light appears as a column, brighter at the horizon, tilted at the angle of the ecliptic. The light scattered from extremely small dust particles. The source of the dust probably originated from the tails of active comets.

There is color variation of the photo
