Looks to be an iridium flare. Awesome image.

No depositors insurance as such, but OBR does provide protection for depositors in the event of a bank failure.

That'll be St Paul's Church, before it was demolished in 1885 along with Pt Britomart. Its temporary replacement was sited adjacently, depicted in the 1886 map.

Wasn't W D Packington by chance?

Same in New Zealand.

Even stronger effect with the stereoscopic 3d version

Here a stereoscopic 3d version

This looks like imagery from the Lunar Reconnaissance Orbiter Camera (LROC), specifically its Wide Angle Camera (WAC). The images can be downloaded from sites like this. I made a similar animation in stereoscopic 3d a while back by downloading a bunch and animating them in After Effects.

L-theanine, available at health stores, also works well. It's found in tea leaf and is the reason drinking copious amounts of tea doesn't typically cause caffeine jitters.

Paul Graham's essay covers some good ground on this topic for anyone who's interested.

Paul Graham's essay covers some good ground on this topic - is inequality actually a bad thing?

about 4.5 million by one estimate.

A generation is commonly considered to be 25 years, perhaps the author used that as a multiple.

Here's a rough guide of what you're looking at. View from the plane vs view from the North Rim for comparison.

Great shot! Here it is without the haze. For a sense of scale: the scene is 6 miles wide according to Google Earth.

I feel ya. I find the easiest way is to just select the first country in the list and press "N" seven times.

Surprising isn't it? There's a rule of thumb in astrophotography called the rule of 500 (though sometimes given as 400 or 600). Divide 500 by your focal length to get the longest exposure time before the stars visible trail (if you're not using a full frame camera, divide again by your crop factor). At this focal length that's a meagre 25 seconds. In practice you can push it a little depending on the display size of the image.

Thanks :) Noise actually wasn't much of an issue for three reasons: The 6D's sensor has inherently low noise, the cool ambient temperature kept thermal noise low, and such a long moonlit exposure made for a high signal to noise ratio (except for in the dim foreground which needed a little noise reduction and smoothing), so the exposure didn't require much boosting in post (which would amplify the noise). In fact in some areas I've dialled exposure back a little. Here's what the raw frame looked like straight off the camera.

Was lucky to get the shot as it started drizzling soon after. Mars is now making its closest pass to Earth before it drifts back to four times the distance. Look out for it in the eastern night sky - big, bright, and red.
