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.
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.

A mix of sky glows fills the pre-dawn sky in New Mexico.
To the eye the sky looked dark, marred only by some high haze drifting through. But the camera reveals a sky filled with an amazing wealth of colourful glows.
I took this 360° panorama in the pre-dawn hours (4:45 a.m.) this morning (December 8) from the Painted Pony Resort in southwest New Mexico. It reveals a swath of green airglow to the north, the zodiacal light, and the Milky Way. At northern latitudes there was bright aurora visible last night. We might have seen some sign of it here in New Mexico in the form of increased airglow activity.
The panorama takes in, from left to right:
• Arcturus, shining like an ornament on the treetop
• the zodiacal light rising up from the east
• red Mars embedded in the zodiacal light below Leo
• the Milky Way from Puppis and Canis Major at left arching up and across the sky down into Perseus at right
• Sirius the brightest star
• Orion setting over the main house
• Jupiter, the bright object at top centre in Gemini
• Aldebaran and the Pleiades setting right of the main house in Taurus
• Polaris over the smaller house at right
• the Big Dipper at upper right pointing down to Polaris
• a green glow along the northern horizon above the smaller house that is likely intense airglow.
• green and red bands throughout the sky are airglow, caused by atmospheric molecules flourescing at night
• bands of high cloud also permeate the sky adding natural glows around the stars.
I stitched this panorama using PTGui software, from 6 segments, all tracked, taken with the 14mm Rokinon lens at f/2.8 for 2.5 minutes each and with the Canon 5D MkII at ISO 1600.
As a postscript — this is blog post #401 from me.

The Zodiacal Light shines bright in the New Mexico dawn, near where the ill-fated Comet ISON would have been.
This was the dawn sky on the morning of December 6, 2013 looking east from our observing site at the Painted Pony Resort in New Mexico.
The zodiacal light was bright pre-dawn extending up from the horizon to high overhead. This glow is from sunlight reflected off comet dust in the inner solar system.
Adding to that cloud of dust is presumably the remains of Comet ISON (C/2012 S1) – this image includes the position where ISON would have appeared had it survived, with its head left of centre, just left of the zodiacal light, and just above the mountain ridge. Its tail would have arched up and to the left, had it grown an extensive dust tail as was hoped.
As it is, there is a comet in the field – Comet Lovejoy (C/2013 R1) is a tiny blue blip at far left, a minor consolation prize for missing ISON. Pity ISON didn’t work out, as we would have had two photogenic and naked eye comets in the dawn sky together.
The field also contains two planets: Mars in Leo above and right of centre, and Saturn in Libra just coming up over the mountains in the middle of the zodiacal light. Both lie in the zodiacal light because the light follows the ecliptic – i.e. the plane of the solar system and the orbits of the planets.

Comet Lovejoy shines above the New Mexico desert in the pre-dawn sky.
We came here for Comet ISON but have had to settle for Comet Lovejoy, a decent enough comet in the morning sky, but not the spectacle we had hoped for.
This was Comet Lovejoy (C/2013 R1) as it appeared this morning, December 6, under very good New Mexico skies marred only by some scattered clouds and patches of airglow. The main image is a 50mm lens shot of the wide scene looking east.
The comet was visible to the naked eye, but just barely as a fuzzy star. It took the long exposure photos to bring out its blue ion tail, stretching 6° to 10° across the sky and pointed down toward the sunrise point in the east.
I took the close-up shot above with a 135mm telephoto lens showing the bright head and faint ion tail. The tail here measures 6° long, though a deeper exposure might have picked up more, up to 10° long. But I think reports of seeing a tail up to 5° long with the naked eye are wishful seeing. The comet and tail are not that obvious, and we are in superb skies.
Still, Lovejoy makes a fine comet consolation prize, substituting for the ill-fated Comet ISON. It was a beautiful morning to enjoy Lovejoy in the quiet and star-filled New Mexico dawn.

The waxing crescent Moon shines above Venus and our adobe house in New Mexico.
Tonight, December 5, the clouds cleared in time for us to catch a glimpse of the crescent Moon above Venus, now at its most brilliant for the year.
They shine above the main house at the Painted Pony Resort where I am this week for a stint of astrophotography with a dozen other Canadians escaping winter up north. But it’s cold here, too – it might go down to freezing tonight. Horrors!
For this shot I made liberal use of shadow and highlight recovery at the Adobe Camera Raw stage and in Photoshop to recover as much detail as I could in the overexposed Moon at top. However, the long exposure nicely brings out the stars in the moonlit sky. I also like the contrast of pastel colours.

Jupiter and the stars of the winter sky rise in the east on a December night in New Mexico.
This was the scene last night, December 4, as clouds cleared away enough for great views of Orion and the winter sky rising above distant mountains in New Mexico. (All the clouds, that is, except for one annoying dark blob in Gemini above Jupiter!)
The bright object at lower left is Jupiter, in Gemini this winter, rising with Castor and Pollux to the left of Jupiter. To the right of frame Orion comes up on his side, with his Belt pointed down to where Sirius will come up shortly after I took this image. The red-sensitive camera picks up swirls of nebulosity around Orion.
Above Orion are the stars of Taurus and Auriga.
This image is a framing of the Milky Way from Perseus at top right down to Taurus and the top of Orion at bottom left. At centre is the blue Pleiades star cluster, and the red arc of the California Nebula. Also at centre you can see the long dusty tendrils of the Taurus Dark Clouds, interstellar clouds between us and the Perseus arm of the Milky Way.
I shot both from the Painted Pony Resort in southeast New Mexico using a little iOptron SkyTracker and 2.5- to 3-minute exposures with a filter-modified Canon 5D MkII.

The subtle glow of zodiacal light competes with the artificial glow of light pollution.
This was the scene earlier this evening, December 4, from our dark sky retreat at the Painted Pony Resort in southeast New Mexico. In the distance the yellow glow of light pollution reflecting off the clouds comes from Douglas, Arizona.
Above, in the sky, you can see a subtle band of light reaching up and tipped slightly to the left. That’s the zodiacal light, caused by sunlight reflecting off cometary dust in the inner solar system.
At right is part of the summer Milky Way, setting into the west.
The clouds are orographic clouds hovering over the Chiricahua Mountains, where I was last evening shooting the sunset.
Our first night here has proven to be much better than we had expected, with scattered cloud but mostly clear skies. We’re here for another 4 nights. More is coming!
