A few hours before the war began - Night Sky

 Something wrong was at this night. Even tripod was broken. Clouds cover all sky in couple minutes. In a few hours the war began.

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.

Sky Ladder - Galapagos Nightscape Astrophotography

The Night Sky at Galapagos Islands is one of the best dark sky which I saw! The darkness of night sky based on Bortle scale was very close to Level 1 (Excellent dark-sky site): clouds are only visible as dark holes against the sky, airglow is readily visible. I did not see a lot of night photos at Galapagos in internet, but I think it will be a lot soon, it is really one more attraction on the islands.

Green Sky Utah Airglow Astrophotography Canon 60Da

The sky is green, the night is dark - as simple as possible. This photo was done at Bryce Canyon, Utah. Canon 60Da, EF16-35mm f/2.8L II USM, 30.0 sec; f/3.5; ISO 6400

Green Sky Utah Airglow Astrophotography Canon 60Da

The natural moonless night sky is dark but not black; it is not even blue (no scattering light from sun and moon). Earth atmosphere  emits green, red, orange, yellow light- Airglow!

About 60% of the natural brightness of the night sky at zenith is made up of Airglow. Maximum brightest usually appears at about 10-15 degrees above the horizon, because of the greater the depth of atmosphere at this angle. Airglow is not always uniform. Gravity waves may create considerable variation of Airglow brightness.

You can see Airglow only in real dark sky, but naked eye could not recognize colors. Photos with long exposure able get the colors of Airglow.

The usually dominant color of airglow is green originated from molecular oxygen at 90 to 100 km high. Orange and reddish hue caused by atomic oxygen in 150-300 km above the ground, Yellow light comes from sodium atoms in a layer at about 90 km.

Night sky with green Airglow, the Milky Way, Seven Sisters and Andromeda Galaxy is on the top; hoodoos, caused by erosion over many millennia are on bottom.  This photo was done from my trip to Bryce Canyon in Sunset Point.

On this picture you can see a lot of green color on the sky. If this is real color or just effect of camera filter? This question directly connected to other question “What is natural color of night sky?”

I started to learn astronomy many years ago reading the book with black and white pictures. So in these books I didn't see color picture of the natural sky. Most of time I was living in big city with a lot of light pollution, and I am not able to see natural color of sky.

Still remember when first time recognize that some starts has color and after that read article about color of stars cannot be green. After that article I assumed that green color is very rear on the sky. But this is not correct.

Most of Comet Tails has green color. Some Nebular are green too. Northern Light mostly has green colors. But Northern Light visible only near North Pole, comets are rear so still assume that this green colors are exceptions. When I started see Internet picture I saw a lot of strange colors so assuming that these is Photoshop. Especially after reading article how to remove light pollution in Photoshop. And only made some my own pictures I recognized that green color from Airglow effect is gives a lot of green on the natural sky. So a green color is pretty common on the natural sky too.

iOptron SkyTracker Astrophotography Equipment

Equipped with his five senses,
man explores the universe around him
and calls the adventure Science.
--Edwin Hubble

My dreams happen in reality and I got iOptron SkyTracker! Still using piggy pack of the Celestron 4SE I can track sky by camera at home but it too heavy to get the telescope to the long trip. The SkyTracker is pretty compact and not so heavy and can do the same – follow the rotation of the sky. So fly by air plane to places with dark sky I can get more stars, the Milky Way during one shot, increasing camera exposure.   iOptron SkyTracker pretty much can handle Canon 60Da with Wide Angle EF 16-35mm f/2.8L II USM or Telephoto EF 200mm f/2.8 L II USM lens.
