Orion and Canis Major Rising


Sirius & Canis Major Rising from New Mexico (35mm)

Canis Major and Orion rise into the desert sky from southwest New Mexico.

We had an excellent week of observing at the Painted Pony Resort. We had cloud on parts of most nights, and frost on the calm nights and wind on the frostless nights. So viewing conditions weren’t ideal but they were way better than back home where temperatures plunged to -35° C at night and snow piled waist high.

The shot above is of Sirius and Canis Major, the hunting dog, rising into the early evening sky after the Moon had set.

Orion Rising over Adobe House v2 (New Mexico)

I took this image later in the week. It shows Orion rising above the main adobe house at the resort. His Belt points down to Sirius just coming up over the Peloncillo Mountains to the east. Moonlight provides the illumination and bands of airglow colour the sky.

All-Star Telescope is conducting another New Mexico Star Party next March, but most spaces are already filled. A couple of rooms may still be available in a newly renovated cottage off the main resort site. Check with Ken and Bev for details. I highly recommend the experience.

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.

An Orion Portrait from Alberta


Orion in Porttrait Format

He’s certainly the sky’s most photogenic mythological figure. Here’s my full-length portrait of Orion the hunter, captured from Alberta.

I’ve shot him many times before but this was a new combination of gear: the Canon 60Da camera and the Sigma 50mm lens, nicely framing the hunter in portrait format. This version of Orion isn’t as deep as the one I took last month from Australia. But skies were darker there, and I used my filter-modified Canon 5D MkII for his Oz portrait, a camera which picks up more faint red nebulosity than does the 60Da, Canon’s own specialized DSLR camera for astronomy. The 60Da does do a very good job though, much better than would a normal DSLR.

For this shot, as I do for many constellation images, I layered in exposures taken through a soft-focus filter, the Kenko Softon, to enlarge and “fuzzify” the stars! It really helps bring out their colours, contrasting cool, orange Betelgeuse with the hot blue-white stars in the rest of Orion.

I shot this January 4 on a fine clear winter night, the classic hunting ground for Orion.
