Orion and His Hunting Dogs in the Milky Way


Orion and Canis Major Panorama

Orion parades across the northern winter sky followed by his two odedient hunting dogs, Canis Major and Minor.

I shot the images for this panorama of the winter sky last night, December 6/7, on a frosty and cool night at our retreat in New Mexico.

The scene takes in Orion at upper right, with his signature stars, red Betelgeuse and blue Rigel, plus the dog stars Procyon at upper left (the brightest star in Canis Minor), and Sirius at lower centre (the brightest star in Canis Major). Canis Major itself appears in full at the bottom of the frame. Canis Major and Minor are depicted in mythology as Orion’s two Hunting Dogs .

The northern winter Milky Way runs from top to bottom of the frame, punctuated by patches of red nebulosity such as the circular Rosette Nebula above centre. Orion is wreathed in the sweeping arc of Barnard’s Loop, while his Belt and Sword contain the Horsehead Nebula and Orion Nebula.

While we are looking to the outer edge of our Galaxy in this view, this region of the Milky Way is one of the richest areas of star formation in the sky. It’s a wonderful field and lovely to shoot under civilized conditions in southern New Mexico, at the idyllic Painted Pony Resort.

For this mosaic, I shot 4 to 5 frames for each of the two mosaic segments, plus two images for each segment shot through a diffusion filter to add in the accentuated star glows. I stacked and stitched all of them using Photoshop CC.

So a total of 13 exposures went into the mosaic, each 4 minutes long, shot with the 35mm lens and filter-modified Canon 5D MkII, which helps bring out the red nebulosity.

As a footnote — this is Blog post #400 from me.
