Earthshine Photos

[chrisyeo]

The sky was clear tonight and the moon was really spectacular, with the earthshine clearly obvious to the naked eye. Here are some photos I took:

Here's a closeup.

For those who don't know, earthshine is light that reflects off the earth unto the moon and back on to us again.

Cheers,
Chris

Nice shot, Chris. I gather from the false colour that you did not use the 6" reflector? Any details on the exposure or equipment used?

Thanks Kay Heem,

The pictures were taken directly with my digital camera, since I was out and had it with me.

Here are the details for the photos:
Earthshine2: Exposure 10"; ISO 100;3x Optical Zoom
Earthshine1: Exposure 1"; ISO auto; 3x zoom; exposure compensation +2
Earthshine3: 6"; ISO 100; 12x zoom (4x digital);

I balanced the camera on the roof of a car and used the self-timer to take the shots. The camera is an Ixus 500.

Cheers,
Chris

Hi,
Can we tell just by looking at the moon that we're seeing an Earthshine? How? If not, then how do you recognise an Earthshine??

Thanks.

Hi Dark Prince,
By process of elimination. There's no other lightsource there except for reflected light from earth. the stars probably add a little but I doubt we can actually distinguish it.

Hi Dark Prince,

All you have to do is for example look out tonight for the moon. On certain evenings when the sky is clear and the moon is a crescent, you will still be able to notice a faint outline of the full moon. What you are seeing is earthshine.

Cheers,
Chris
