Imaging moment | magnificent special natural phenomenon

Whenever the night falls to look at the starry sky,

Vast universe

It is also like a colorful picture,

Slowly showed in front of the world.

Colorful, colorful,

The beautiful "night sky",

Always stimulate people's endless imagination!

2020 Gemini Meteor Shower of Gien

Author: Luo promoted

Shooting time: 2020/12/13-12/14

Shooting location: Eye of Gie Xue Mountain, Liexue Mountain, Litang County, Ganzi Prefecture, Sichuan

Shooting equipment and parameters:

Canon EOS R5 camera, Shima 14mm f/1.8 art lens, Starry Sky: Star Equator Instrument exposes for 1 minute; Scenery: Close the equatorial instrument, a total of 126 stitching of the world; Meteor: A total of more than 230 inner meteor photos are superimposed on the stars.

Introduction of works:

Gieie Snow Mountain is located in Litang County, Ganzi Prefecture, western Sichuan. At the foot of the east side of the Gieie Snow Mountain, the eyes of Gidie were like a eye when overlooking from the air, and was praised by netizens as "the eyes to heaven."

On the 2020 Gemini Meteor Shower Night, my wife and I came here and recorded the meteor all night with 6 cameras; we put on the Tibetan robe and sprinkled this memorable Gemini meteor rain dog in a responding way. grain.

This picture of the meteor is a scientific superposition to the sky, the stars, and the radiation point, and more than 230 internal meteors are selected.

The picture contains the winter galaxy, Hα star cloud, meteor, Mars, zodiac light, qi, etc.; The meteor shot from the radiation point of Gemini, forming a "rain" general visual effect.

Important techniques used during shooting:

1. If you want to take a better long exposure to shoot the starry sky, you must use the equatorial instrument. This picture of the starry sky uses the equatorial instrument to track and shoot, followed by closing the equatorial instrument to use the same parameter to shoot the landscape. The shooting position of the starry sky and the landscape part cannot be changed, and the interval between photos is very short, so that scientificity can be guaranteed when stitching synthesis.

2. The position of the meteor is strictly superimposed with PTGUI software, instead of adding it to the figure at will.

Later processing method: 1. Use RAW format photos to import Photoshop for adjustment of color temperature and brightness. 2. Guide the diagram of the starry sky into the PTGUI stitching to generate a panoramic view of the starry sky. After the output is output, the group of meteors in the shot is automatically allowed to automatically align the stars to stack the meteor. Finally, the two starry sky stitching panorama maps are finally output. Zhang has no meteor. 3. The landscape part is also introduced into PTGUI stitching to generate panoramic views and output.

4. Then import the three panorama into the PS and synthesize alignment and ground.

5. Then use the "Jeff noise reduction process" and the Topaz Denoise AI software for noise reduction treatment. 6. Finally, use liquefied tools to modify the characters slightly and out.

"Phantom" meteor

Author: Niu Qian

Shooting time: 2020/12/14

Shooting location: Ulan Buki, Xilingule League, Inner Mongolia

Shooting equipment and parameters: Sony A7S3 camera, Sony 24mm f/1.4 lens, f/1.4, ISO102400

Introduction of works:

In the early morning of December 14, 2020, the peak moment of the Gemini meteor rain traffic is the year.

In the Xilinule League of Inner Mongolia Autonomous Region, in a harsh environment of minus 35 degrees, I used the Sony Alpha 7s3 camera to take a dazzling meteor of night sky and ground photographers. This scene caused the photographer's excitement.

This shining meteor produces a rare 22 ° dizziness, which is an unprecedented scene in the previous starry sky shooting, and it is named for the first time: fantasy meteor.

Important techniques used during shooting:

Choose photographers and equipment as the prospects, and record the love of astronomical enthusiasts in the starry sky in the cold environment of minus 35 degrees.Later processing method: After coloring in Davinci Resolve, static frame grasp is performed, and the Photoshop stack is used for noise reduction.
