This wide-angle image takes in the northern spring sky from horizon to well past the zenith at top. At top is the Big Dipper and Ursa Major. Below it is Leo and its bright star Regulus. At left is Boötes and the brightest star of the spring sky, Arcturus. At lower left is Virgo and its bright star Spica. The cluster of stars at centre is Melotte 111 in Coma Berenices. At bottom to the right of Spica is the trapezoid of Corvus. The constellation patterns at bottom and top are skewed somewhat by the wide-angle lens distortion.

The image serves as an illustration of how the Pointer Stars of the Big Dipper's Bowl point down to Leo. The curving arc of the Dipper's Handle arcs down to Arcturus, while extending that line "speeds you onto Spica," a common way to find your way around the spring sky.

At centre is the North Galactic Pole (NGP), the point 90º away from the band of the Milky Way, and home to many other galaxies beyond ours.

Technical:
This is a stack of 10 x 1 minute exposures with the Canon RF15-35mm lens at 15mm and wide open at f/2.8 on the Canon EOS R camera at ISO 800. It was on the Star Adventurer 2i tracker. An additional exposure layered in taken through a Tiffen Double Fog 3 diffusion filter adds the star glows to accentutate the constellation patterns and star colours. Taken from home in Alberta at latitude 51º N on a very fine night in April 2025.

Still learning but happy with the result.

A barred spiral galaxy often called the Vacuum galaxy.
Found in the constellation of Ursa Major some 60 million light years away, it's estimated to contain around 1 trillion stars.
Several other galaxies are also visible.

- www.kevin-palmer.com - It wasn't supposed to be clear this night. But since I was out camping I was able to catch the brief clearing when the stars came out.
