This is a 200° panorama of the arch of the northern Milky Way rising over the Badlands landscape of Dinosaur Provincial Park, Alberta. This was the night of May 31/June 1, 2024, when from this latitude of 50° 45' N the sky is not fully dark even in the middle of the night, here at about 1:30 a.m. MDT. So the sky retains a blue tint, especially to the north at left. So this records a colourful sky that contrasts with the earth tones of the Badlands landscape of eroded bentonite clay hoodoos, iron-rich rocks, and sagebrush. And I like the field of white flowers mimicking the stars above. Adding to the sky colours are bands of green oxygen airglow, especially at centre to the east, and perhaps yellow sodium airglow at right. At left to the north the horizon is tinted pink from a faint arc of aurora borealis. A Kp5 show of Northern Lights was predicted for this night but nothing of the sort materialized! The mass of stars toward the galactic centre at right in Sagittarius and Scorpius also glow with a combined yellow light, in part due to absorption of shorter wavelengths of starlight by interstellar dust in the spiral arms of the Galaxy. It is that obscuring dust that creates the dark regions along the Milky Way, splitting the Milky Way starting in Cygnus at top and extending at right down into Serpens.. The stars also have their own colours, such as blue Vega at top and yellow Arcturus at upper right. Yellow Antares in Scorpius shines above the hoodoo at lower right. But the most striking sky colours are the red and magenta from glowing hydrogen gas in star-forming nebulas along the MilkyWay and toward the galactic core rising at right. I emphasized those through the use of a filter that isolates that red wavelength of "hydrogen-alpha" emitted by the nebulas. The most obvious H-alpha feature is the large round nebula at right, Sharpless 2-27 surrounding the star Zeta Ophiuchi above Scorpius. The red nebulas in the Milky Way to the left of Sh2-27 are from
