Good morning, Rallypoint. Today's Astronomy Picture of the Day (AOD) is titled "A Path North." Two things amaze me about this image from Lower Saxony, Germany: 1) the number of colors in the sky, and 2) what a four-hour exposure can tell us about our world (the zig zag up the hill is the photographer). Isn't it amazing how reality can be made to resemble fantasy?

Good Monday, April 7, 2020 my friend Maj William W. 'Bill' Price and thank you for posting the NASA Astronomy Picture of the Day (AOD) for today entitled "A Path North."
This is a familiar image

1. A Path North - Image Credit & Copyright - Mario Konang
2. 1889 Vincent van Gogh – The Starry Night, 1889
"Explanation: What happens if you keep going north? The direction north on the Earth, the place on your horizon below the northern spin pole of the Earth -- around which other stars appear to slowly swirl, will remain the same. This spin-pole-of-the-north will never move from its fixed location on the sky -- night or day -- and its height will always match your latitude. The further north you go, the higher the north spin pole will appear. Eventually, if you can reach the Earth's North Pole, the stars will circle a point directly over your head. Pictured, a four-hour long stack of images shows stars trailing in circles around this north celestial pole. The bright star near the north celestial pole is Polaris, known as the North Star. The bright path was created by the astrophotographer's headlamp as he zigzagged up a hill just over a week ago in Lower Saxony, Germany. The astrophotographer can be seen, at times, in shadow. Actually, the Earth has two spin poles -- and much the same would happen if you started below the Earth's equator and went south."
The image brought to mind a Pink Floyd from decades ago.

Thank you, my friend TSgt Joe C. for mentioning me.

LTC Stephen F. and Maj William W. 'Bill' Price Great pictures and details in *both* of your posts.
And a sidebar azimuth/declination comment: As for *A —path— North* —-> used to prep folks for LandNav testing with the caveat “if you start on the South Pole, every direction is in fact North. ” And even that is subject to variation be it “true” North, magnetic, “North* Carolina or Santa’s House, the Uwharrie “bush monster” stripping your (unsecured by “idiot cord”) compass notwithstanding on an overcast non-starry and moonless night in the rain. Happy Tuesday to *All.*
LTC Stephen C. Hope *Mackall* well in your GPS grid coordinate!
