RATTKIN: Dal jsi tu polárku do rohu, takže ti to tam protahuje jako každej širokej objektiv.

RATTKIN: na architektuře si myslím nemáš šanci si toho všimnout pokud zrovna nefotíš pravidelné obrazce. Řekl bych že to je prostě soudkovitost a třeba Photoshop by to s profilem objektivu asi srovnal automaticky. Myslím, že když bys měl zemskou osu víc uprostřed než ji máš teď, tak by sis toho nevšimnul, protože uprostřed je to zkreslení menší než na okrajích.

mám dotaz:
konečně jsem vyfotil rozumné star trails. Proč to mám oválný a ne kruhový?

pardon za repast, ale gif imo lepší :)

JOSE_MAT: yeah, same as landing on the moon ;)

The far side of the moon, illuminated by the sun, is seen as it crosses between our 'EPIC' camera on the Deep Space Climate Observatory (DSCOVR) satellite, and the Earth - one million miles away. Check it out: http://go.nasa.gov/1Dq0IO9

Muheheheheehe ne primo z vesmiru, ale souvisi. Buzz Aldrin zverejnil na Twittru "cestak" na mesic, ktery musel jako sluzebku vyplnit po navratu z mesice :-D :-D

Mars

"This image shows a remarkable double crater with a shared rim and North-South trending ejecta deposits. These two craters must have formed simultaneously.
The bolide may have consisted of two objects of the same mass that were loosely connected, perhaps similar to comet 103P/Hartley 2, which the Deep Impact spacecraft (EPOXI mission) encountered on 4 November 2010 (see here). Many more asteroids than comets impact Mars, but asteroids also come in double shapes, like asteroid Itokawa explored by the Japanese Huyabusa mission. The bolide must have separated into two distinct pieces prior to impact in order for two craters to be recognizable."

Start raketoplánu focený z vesmíru (tilt-shift photography)

A NASA camera on the Deep Space Climate Observatory satellite, nicknamed DSCOVR, has taken its first image of the whole sun-lit side of Earth.

The high-resolution photo from NASA's Earth Polychromatic Imaging Camera (EPIC), released on Monday (July 20), was taken on July 6 from a distance of 1.6 million kilometres (one million miles.)

It's the first view of the entire sunlit side of Earth at once taken since Apollo 17 astronauts captured the iconic "blue marble" photograph in 1972. Subsequent images released of the whole Earth have mostly been mosaics stitched together with image processing software, NASA says.
