Before going to meet Super Blue Moon – Super Full Moon tonight, August 30, 2023, NARIT introduces techniques for capturing impressive moon images. Prepare yourself before going into the real field.
On August 30, 2023, the National Astronomical Research Institute (Public Organization) (Dr.), Ministry of Higher Education, Science, Research and Innovation disclosed through the page. NARIT, National Astronomical Research Institute Specify ready to shoot. The largest full moon of the year before meeting with Super Blue Moon Introducing techniques for capturing images the moon Impressive. Prepare yourself before entering the real field. On the night of 30 to the morning of 31 August 2023, there are 2 phenomena of the moon, namely
Super Full Moon or The full moon is the closest to Earth in a year. It is approximately 357,334 kilometers from Earth and that night is also the second full moon of the month or blue moon (Blue Moon)
on that night full moon Will appear slightly larger than usual. Compared to the normal full moon It is about 7% larger and about 15% more brightness. This is the right time to observe the lunar phenomenon. Is the evening of August 30, 2023 from about 6:09 p.m. until dawn on August 31, 2023, can be seen with the naked eye in the east. Saturn also appears bright alongside the moon.
On such nights, the full moon will appear slightly larger than normal. Compared to the full moon at the farthest from the Earth in the year. It may be up to 14% larger in diameter and up to 30% brighter as a result of the Moon being closer to Earth. Size appears larger thus seeing brighter Good for photographing the moon Especially the image comparing the size with the object on the horizon.
each month The moon orbits the earth in an ellipse. causing the distance between the Earth and the Moon to be unstable Close to the world and far from the world alternately. Astronomers call the location where the moon is closest to Earth called Perigi (Perigee) has an average distance of approximately 357,334 kilometers and the farthest position in the world is called Apogee (Apogee) with an average distance of approximately 405,818 kilometers
the word part “Super Full Moon”It’s just naming the range of events that “Can see the full moon In the position closest to the world in the year only, is not a name in science.
Here are some basic knowledge about taking pictures of the moon:
1. Use a telephoto lens with a focal length of 300mm or more to get a large image of the moon. The more photographed through a telescope with a higher focal length, The larger and more detailed the moon is, the better.
2. Use an ISO sensitivity of 400 or higher as the full moon is already very strong. High sensitivity is not required. But using a high sensitivity will result in a higher shutter speed as well Help to make the image not flicker.
3. To adjust the focus of the image, it is recommended to use the Live View system on the screen behind the camera. Selective focus on craters on the lunar surface. It will help to focus sharply and easily as possible.
4. Adjust exposure compensation to not be too bright or too dark May try to take pictures and check the images to see if the details of the holes on the moon are clear or not.
5. Use manual shooting mode (M), as both aperture and shutter speed settings can be easily adjusted.

6. Shutter speed It should be related to the focal length of the lens used. For example, if using a lens with a focal length of 600 mm, the shutter speed should be at least 1/600 sec. If the image is taken too dark, increase the ISO sensitivity. ) up until the light is just right.
7. Aperture Choose from approximately f/4.0 – f/8.0 for a sharp image throughout the entire image. Turn off the lens stabilization system.
9. Shoot on a stable tripod
10. Data recording should be selected as RAW format for flexibility in post-processing.
Once the basic principles are known, they can be applied to take pictures.the moonTo be interesting, such as taking pictures of the moon, comparing the size with objects in the horizon or Moon Illusion to show the apparent size of the moon in the closest range to the earth. Because the moon on the horizon often has objects comparable to the size of the moon. makes observers feel that the moon is large The photographer had to figure out where the moon would rise from the horizon. And the object to be photographed to compare the size with the moon. And there should be a distance of several kilometers from the photographer.
