In the explanation it mentions "land and sky justapositions". Is justapositions the US spelling of juxtapositions or is it likely to be just a typographical error? Please accept that this is not a criticism, as I just like to know. Thanks. :ssmile:

The hamlet of Buford in Wyoming is not even a sparsely-populated area. It’s a single-populated area, as the 60-year-old is the only man, woman or child living there. But even though the ‘population one’ hamlet is 8,000ft up a cold mountain, he denies feeling lonely and runs an isolated petrol station and convenience shop.

Mr Sammons left Los Angeles in 1980 with his wife and bought the tiny town with six buildings to escape their busy lifestyle. When the couple moved there were seven people living in Buford working for a railroad that passes nearby, but they all moved away to bigger towns by the mid-1990s. Then his wife died 15 years ago and his son, now aged 26, moved to Colorado three years ago. So that left Mr Sammons in Buford on his own.

He gets about 1,000 visitors a day to the village during the summer, which has a billboard proclaiming his small empire, but this drops to around 100 during the winter. ‘They stop because they're intrigued to find this place in the middle of nowhere near the top of a mountain,’ he said. ‘We sell all kinds of souvenirs from hats to mugs. The post card is our best seller. ’I'm glad to go back to my house after a 10-hour day talking to folks so I can get some peace and quiet. After I close I'm the only guy for miles around. And I like it that way.’ Mr Sammons turned a school house, which operated between 1905 and 1962, into his office and made another old store built in 1895 into a four-car garage. He lives in a three-bedroom log cabin and enjoys a commute of 200 yards to his workplace. ‘I'm the king of the castle here,’ he said.>>

I think it is. Leo is below and to the right of it.

By the way, don't miss the Double Cluster of Perseus in the lower left part of the Milky Way band.

Having taken a similar picture myself, I notice that the horizon has two breaks in it. The line of fences on the left points (roughly) to the middle of the broken part. Also, the leftmost 100 pixels or so are a repeat of what is to the right of them (at least for the ground). The horizon break is inevitable, as the long exposures mean that by the time you shoot all 360 degrees, the stars have moved. But as you stitch the parts to make the stars coincide, you have to move the ground to compensate.

There are stars shining in the landscape. There are shadows, but they run in directions that are counter to the light. There is also a sun and a moon, not unusual, but the moon is in night mode while the sun is in day mode.
Thanks Robert Arn. It is beautiful.

I'm curious... Where do you perceive the sun to be in this image?

The Sun and Moon do not look like they are in Sagittarius?

The Moon is opposite the Sun when full.

This image wasn't made during the full Moon, however.

The colors are there, but our night vision is not sensitive to them.

It's a panorama, so it shows the western and eastern horizon.

It's a panorama, so it faces the light source and faces away from the light source.

The shadows aren't as strange as people might think. This is an extremely wide panorama and you should imagine the swing of a compass needle if you were there at the scene and you were turning around in a complete circle. There are, quite appropriately, two vanishing points for the shadows. One should be at the moon and the other should be 180 degrees away. Left of center the shadows all radiate from the main light source, the moon. The Ames Monument is East of the observer (witness the tripod shadow), with Cheyenne also due East and directly behind the monument. The shadows appropriately converge in the direction of Cheyenne, pointing at the monument along the way. The least distorting way to view this image would be to print it out very large, curve it in a band with the printing on the inside curve, and view it from the center of that arc. You will have to turn your head to scan the full range of the image just like if you were at the scene yourself - and things on the ground would then look very close to normal to you.

Laramie is NW of the monument and is therefore represented by the orange glow between the moon and Cheyenne. I think that the green glow might come from the industrial site, possibly a mine or quarry, that is West of the monument and readily visible in Google Maps.

The image does not appear to be a full 360 degrees because conspicuously absent is any trace of the glow that should be coming from Fort Collins, Greeley, Denver, etc. in Colorado which should have outshone the Cheyenne glow. I suspect that at least some surface lights in Northern Colorado would probably be visible from the Ames Monument but I'm not seeing any here.

This image appears to have been stitched from three fisheye images (aimed West, Northeast, and East). Notice the extreme smearing of the details on the ground where the stitching software had to work very hard to bring together the ground details between what I guess were West and Northeast images, a little too far apart from each other to promote a good seamless stitch.

If that's the setting Moon, those lights are Laramie, not Cheyenne.

No. The view is towards the north. The azimuth of the monument is about 80°, which is straight towards Cheyenne. The glow you see on the horizon just to the right of the Moon is Laramie.
