TEMPO.CO, Jakarta - The National Institute of Aeronautics and Space (Lapan) shares tips and tricks to observe annular solar eclipse, which will occur this afternoon, Thursday, December 26, through its Instagram social media @lapan_ri.
Lapan noted that the most important point is eye safety and called on the people to not looking directly at the sun with naked eyes as its high-intensity light can damage the eyes.
The institute recommends using several tools for the observation as follows:
- Pinhole camera
People can use a pinhole camera which is possible to be made by self with simple materials. Many tutorials to create one are widely shared on the internet.
- Sunglasses
Sunglasses for observation of eclipse are not ordinary ones. This kind of glasses has special lenses designed to block out most of the sun's light.
- Binoculars or telescopes
The concepts and principles of the use of binoculars are similar to that of pinhole cameras, yet the image is projected through a magnifying lens, not a pinhole. Binoculars can be attached to a tripod on a suitable surface to make it stand stably.
- DSLR cameras
For observing an annular solar eclipse, do not point the camera lens directly at the Sun as it may damage the camera sensor. Users are suggested to apply a special sun filter to reduce the intensity of light.
To get a large image of the Sun, use a telephoto lens with a focal length of 500-2000 mm. As for the initial setup, people can set the camera with ISO 100, f/8.0, and shutter speed at 1/1000. To have a focus result, adjusting the camera manually and attaching it to a tripod on a suitable surface are advised.
