APOD: Endeavour's Starry Night (2011 Jun 02)
Re: APOD: Endeavour's Starry Night (2011 Jun 02)
Does it strike anyone else that the "city lights" seem a lot closer than 217 miles away?

Keep in mind that there's a tendency to misjudge dimension on images made from low Earth orbit. The horizon is only about 2000 km away; from the ISS you couldn't see coast-to-coast over the U.S., for instance. In addition, nearly the entire optical path length is largely airless, so you are only looking at objects on the ground through a few miles of atmosphere.jskocher wrote:Does it strike anyone else that the "city lights" seem a lot closer than 217 miles away?

FYI, the view is looking to the southwest, looking backward in the orbit. If the photograph time is correct and UT, I believe the shuttle is located somewhere between Vietnam and Hong Kong. What I'm sure of is the star field. To the lower left is the Southern Cross & Coal Sack near the horizon. The fuzzy spot left of the shuttle and 45°up from Crux is Omega Centauri.

Does anyone know how long the exposure was for this picture?
Thanks.

I, for one, like Roman numerals.

The image was made with a Nikon D3S, a 3-second exposure at ISO 25600, using a 20mm lens at f/2.8.Aescens wrote:Does anyone know how long the exposure was for this picture?

Hands down, THE best image I've ever seen taken from space, and that's saying a lot!
BRAVO!

"Lesson number one, Giordano Bruno. When the Sun is up in the sky, you don't see any stars."
You can with a telescope.
And even with the naked eye, for that matter.....but only one good long look is allowed.
