A 300 mm lens aimed at the moon would not have coverage wide enough to include a harbor full of boats. A 300 lens also would not have a depth of field that would put the foreground boats and the background elements such as clouds and moon in focus.

In reality, the apparent size of the super moon is only slightly larger than the sun yet in the video the moon is 5-6 times the size of the sun.

That the video was "photoshopped" and not identified as such begs the question- is the green flash the result of digital manipulation?

There's a lot of moon photography, scenic pictures of conjunctions, montages, space shuttle nostalgia... Would it be possible to get back to actual images taken by the world's best telescopes?

I am sorry to be negative, but it really has been weeks and weeks of scenery lately and not so much of what's new in astronomy.

Only parts (mostly northern) of Brittany have eastern facing shorelines.

In which town/harbor was this photo taken? Was it Loctudy?

starstruck wrote:Well, must say, I really enjoy the variety and breadth of images and subjects featured on APOD; it is what makes it fascinating and stimulating and more than worthwhile coming back to see every day. Almost without exception, there is something new to be learned. And the comments on Asterisk are always enlightening and/or entertaining too! So, today's pic is another good example. I've never seen a green flash at sunrise or sunset myself yet, but that's not going to stop me from looking out for one. I never actually realised you could get the same effect with the moon too, so there you go, something new. Any road up, as we say in my part of the world, this is a visually pleasing composition . . and I enjoyed revealing the geographical location of the photo by zooming out of the map at the 'on the coast' link. Ta very much.
