I am a tad late to the lunar eclipse party, but here is my go at it.

This was taken as the penumbra of the earth hit the full moon at 02:11 and spans over two and a half hours to the last shot which was captured at 04:47.

The frames where taken 105 seconds apart until it slipped behind my neighbors roof.

48 frames making up 134 megapixels...

Nikon D800, Nikkor 300mm, f/5.6, ISO 100 - 1600. Sky-Watcher EQ6 Pro mount.

Kids, don't try this at home: it's almost certainly not a good idea. But for those of you who are interested in physics, note several important points:

(1) The rocket fires under water: that works because it's a true rocket, carrying both fuel and oxidizer on board and not using air at all. The shape of the nozzle is also important, since water has an amazing ability to absorb heat and thus quench combustion; a caul around the nozzle keeps the water from getting at the ignition point from the sides.

(2) The primary explosion creates a roughly circular set of cracks. Those lead to "big" cracks opening up in the ice, as existing seams and weaknesses get expanded. 

(3) Note that the circular cracks become hexagonal (matching the big cracks) as you move outwards. What's happening is that the inner cracks happen first, and then those start the big cracks, which actually spread faster than the round ones, basically moving at the speed of sound in ice. By the time the last round cracks are forming, they're forming in ice that already has hexagonal cracks in it.

(4) Water is an incompressible fluid, which means that the shock waves are going to hit things under water very, very hard. This is likely to be lethal to anything underwater and nearby, and is how dynamite fishing works. The reasons why that's a terrible idea (and is therefore illegal nearly everywhere) are hopefully obvious.

(5) That said, watching things explode underwater is pretty cool.

Matt Henderson has a great blog with more stuff like that! If you are interested in #circles #mathematics #animations you should check his blog:

Matt, I know you probably won't see that here but you should join Google+ with these great circles you are creating ;)

+Debashish Samaddar and +Alok Tiwari thanks a lot for pointing us to Matt and showing us that the post we have previously reshared was just a copy of the original blog post without giving any credit.
It's a shame to see such behavior here on Google+. Sorry for supporting that by a reshare (which is deleted now).

Thanks also to +Alex Ander for the reference to "Circular Gallifreyan" and to +Gideon Rosenblatt for the reference to "a lo-rez Mandelbrot Set" in the first post we had. Sorry guys for deleting also your comments by deleting the post.
