Sea of Serenity

[Gary]

No conspiracy here, I just wanted to share it



Explanation: On February 2nd, a first quarter Moon shone in planet Earth's early evening sky. As seen from a location on the US west coast near Mt. Hamilton, California, the International Space Station also arched above the horizon, crossing in front of the Moon's sunlit surface. The space station's transit lasted 0.49 seconds. This sharp exposure, a well-timed telescopic image, recorded the space station during the transit against the background of the Moon's smooth Mare Serenitatis (Sea of Serenity). The orbital outpost was traveling northwest to southeast (from 2 o'clock to 8 o'clock) at a range of 389 kilometers or about 230 miles. Of course, the Moon itself was 1,000 times farther away. In the remarkable photo, the glinting station also offers a hint of the bluish reflection of earthlight.

How do you get an object that is so close (the ISS) and another much further away (the moon) both in focus at the same time? I've been playing with Astrophotography for little over a year now and I have had objects move through the eyepiece (like high flying planes) while looking at the moon but they were never in focus. if this is possible i'd like to know how to do it. Gary where did you get the photo from?

Never mind Gary I found the photo. now if I can only figure out how they did it.

here's a link to the ISS transitting the Sun

Well to be honest, I was thinking exactly the same thing?????? Maybe there is a conspiracy after all!

that's what I was thinking... it looks more like something in orbit around the moon...but then the object would be much smaller.

Yes! This has been on my mind all weekend, the space station orbits the Earth, whatever this is, it's orbiting the MOON?????

I don't know anything about photography but NASA has an explanation.

Both object are far enough away to use the maximum focal length of the lens...hence they are both in focus.

Well thanks for that buddy!
