  • TEMPO.CO, JakartaThe 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:

    1. 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.

    1. 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.

    1. 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.

    1. 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.
