Moon-rise and Moon-size – September 26, 2018

Scroll down to content

A lovely Moonrise today, with an apparently HUGE orange Moon lifting off the ground. Nice to see in real-time the effects of Earth’s atmosphere on the shape of the Moon.

Equipment: Newton 200mm, F/5, ASI 1600MM with no filter in Binning 2×2.


And since the Moon looks so huge to most people when it is close to the horizon (the Moon illusion), I’ve decided to wait a couple more hours and acquire another sequence with exactly the same equipment, in order to compare the size of our satellite in the two circumstances. The results speak for themselves: not only the Moon is not larger when it is close to the horizon, but it is actually SMALLER! 🙂
