Watch out for Supermoon tonight

“Super Full Moon, or Supermoon, is a full moon that nearly coincides with the perigee — the closest that the Moon comes to the Earth in its elliptic orbit —resulting in a slightly larger-than-usual apparent size of the lunar disk as viewed from Earth,” NARIT said on its Facebook page.

“The perigee is about 356,400km from the Earth, and this year the Moon will orbit as near as 357,370km from the Earth on Tuesday night. Hence, observers will see the Moon about 14 per cent bigger and 30 per cent brighter compared to when it was farthest from the Earth in the past year,” it added.

The NARIT added that observers should look for the Moon as it rises in the east from 7pm.

It also suggested the following techniques to take photographs of the Super Full Moon:

• Use telephoto lens with focal length over 300mm.

• Set the ISO at 400 or over

• Use Live View system from the camera’s screen to adjust the focus by trying to focus at the meteor crater on the Moon

• Use manual mode and set shutter speed in relation to the lens’ focal length. For example: if you use 600mm lens, you should set the shutter speed at least 1/600 second

• Set aperture size at f/4.0 – f/8.0

• Turn off the lens’ anti-vibration system

• Use a stable tripod

• Save the image in RAW format for flexibility in post processing adjustment
