According to National Geographic
In the Northern Hemisphere, the harvest moon is the closest full moon to the fall equinox, which usually happens on or around September 22. That means the harvest moon usually occurs in September. But this year, the September full moon appeared on the 6th, separating it from the fall equinox by 16 days. The October 5 full moon arrives only 13 days after the fall equinox, making it the closer pairing.
For most of us, the harvest is not quite as symbolic as it used to be, we are not so much an agrarian society any more. But it does still signify the coming of fall, the changing of the seasons and as the days grow noticeably shorter, many people feel the coming of winter. For some people that is cause to celebrate, for others a time to mourn the passing summer days.
Tonight we were graced with enough clouds to give some character, but clear skies for a beautiful view of the moon as it climbed into the night sky. It was wonderful given we had rain for much of the day. I decided to take both cameras, the extender, the longest lens we own and the telescope out tonight as the moon was climbing through the cloudy horizon.
The moon played peek-a-boo with us for a while.
But I was able to get several nice shots with the telescope, with and without clouds. The clouds actually seemed to improve the definition of the moon.
The one downside of shooting the full moon is that as bright as it is, you lose the definition and contrast the shadows provide when the moon is lit obliquely, as opposed to straight on. But it is still a beautiful sight to see.
