    I'd imagine it's difficult to take pictures of the dark side of the moon because of all the darkness.

    Because the satellite used to take the photo ( GOES 16) is in a Geostationary orbit 22,300 miles above our equator.

    The "backside" of the Moon is not visible from the Earth. The Moon is tidally locked with the Earth so we always see the same side. We only ever get to see the "backside" from photos taken by spacecraft which have passed behind it.

    You need to catch it within a couple of days of the new moon i.e. when it's a crescent, then with a bit of overexposure you will get detail on the dark side but a tripod is essential.

    The less of the sunlit Moon we see, the more of the sunlit (daytime) Earth is visible from the Moon so the moon gets most 'Earthshine' at the time of the New Moon when the daylight side of the Earth is facing the moon. That's why in clear air (especially at altitude) you can often see the dark side of the Moon when it's a crescent.

    I got this on a Nikon D90 with 0.77s exposure and a 300mm lens.....
