Observing under the Southern Stars


OzSky Star Safari Panorama #2 (March 2014)

The Milky Way arches over our observing field at the OzSky star party in Australia.

What an amazing few nights it has been. We’ve enjoyed several clear nights under the fabulous southern Milky Way. About 40 people from around the world have had access to telescopes from 14-inch to 30-inch aperture to explore the wonders of the southern sky from a dark site near Coonabarabran, New South Wales.

I’ve seen lifetime-best views of the Tarantula Nebula, the Carina Nebula, the Horsehead Nebula, the Omega Centauri cluster, and on and on! But the views of Mars have been incredible, the best I’ve seen the planet in a decade as it is now close to Earth and high in our southern sky.

The panorama above is a stitch of 6 untracked segments taken with a Canon 60Da and 8mm fish-eye lens. Each segment is a 60-second exposure at ISO 3200.

The 360° panorama takes in the Milky Way from Canis Major setting at right, over to Scorpius and Sagittarius and the centre of the Galaxy rising at left. At top centre is the wonderful Carina and Crux area. The two Magellanic Clouds are just above the trees at centre.

At upper left is Mars, and just to the left of it is a diffuse glow – the Gegenschein, sunlight reflected of comet dust in the direction opposite the Sun. Mars is near that point now. You can just see a faint band running from the Gegenschein to the Milky Way — the Zodiacal Band of comet dust.

Observer & Telescope at OzSky Star Party #4 (March 2014)

Here, one of our observers takes in a view through a 24-inch reflector telescope under the stars of the Southern Cross, the pattern in the Milky Way behind him.

The nights have been warm and wonderful, though a little damp and dewy after midnight. However, rain is in the forecast again, a welcome relief for most local residents who want the rain. They can have it now. We’re happy!

Aurora at the Observatory


Aurora over Calgary from RAO (May 25, 2013)

A low aurora appears in the city skyglow and bright moonlight at the local observatory. 

After several days of rain, skies cleared beautifully for a Saturday night star party for the public at the local university observatory, the Rothney Astrophysical Observatory, southwest of Calgary.

The evening was capped off by the appearance, as expected, of an auroral arc to the north. Despite the light from the nearly Full Moon and urban sky glow to the north, the aurora managed to compete and put on a show for a few minutes before fading.

RAO Open House (May 25, 2013) #13

About 100 people attended the evening, and were treated to views of Saturn, shining in the south near Spica. Unfortunately, clouds to the west over the mountains never cleared away enough to allow us views, and me photos, of the triple-planet conjunction of Mercury, Venus and Jupiter. Still, a good time was had by all.

Night of the Comet on a Desert Highway


Comet PANSTARRS & the Moon in Twilight (March 12, 2013)

Sometimes the best sky experiences just happen spontaneously. This was one of them – a night of the comet on a desert highway.

This was the scene at our impromptu roadside star party last night, north of the Painted Pony Resort in southwest New Mexico. About a dozen of us, mostly Canadians, gathered at a highway pull off to watch the unforgettable sight of the waxing crescent Moon setting alongside Comet PANSTARRS. You can see the comet to the left of the Moon in the background wide-field image, more or less as it appeared to the naked eye. But the real treat was the view through binoculars and my own small 80mm telescope. The series of closeups with a telephoto lens captures that view.

It was amazing to watch the comet tail and dark side of the Moon setting together as the last bits to disappear behind the mountains. All the while the winter stars and Milky Way were appearing overhead in a perfect sky, all on a mild desert night. A stunning astronomical experience.

Thank you PANSTARRS!

See, That’s the Orion Nebula!


RAO Open House (February 9, 2013)

What a hardy bunch we are in Canada, braving winter weather to see Orion and company. 

A well-bundled group of sky fans partakes in an impromptu tour of Orion and his famous nebula.

I shot this scene last night, February 9, at the first of a series of monthly stargazing nights at the local university research observatory, the Rothney Astrophysical Observatory. About 120 people and volunteers gathered to take in the sights of the winter sky, as best they could as transient clouds permitted. Inside, speakers presented talks themed to the Chinese New Year, which is governed by the timing of the New Moon each year. As this was a New Moon night, people were able to stargaze under reasonably dark skies to see deep-sky sights such as the Orion Nebula.

Want to know where it is? An astronomy club member points it out rather handily with one of the best tools astronomers have for public outreach, a bright green laser pointer. Controversial and dangerous in the wrong hands, when used responsibly these laser pointers are wonderful for conducting sky tours.

As a side note, this is a 3-second exposure with a new Canon 6D camera at ISO 8000, yet the photo shows very little noise. In just 3 seconds, the Milky Way is beginning to show up! I could have gone to previously unthinkable speeds of ISO 12000+ and still had a presentable shot. This will be a superb camera for nightscapes and available light shots.

The Great Australian Eclipse – Our Happy Group!


OK, one last eclipse post! Here’s our happy band of Canadian chasers, post-eclipse.

Some were seeing their first eclipse. A few others, myself included, were chalking up eclipse #14. Eclipse virgin or veteran, the experience is always breathtaking and unbelievable. Moments after the eclipse ends you cannot believe you saw what you did – the sight is so unearthly. And you want to see another. The next total eclipse of the Sun is November 3, 2013, in the mid-Atlantic and over central Africa.

On the Beach — Stargazing


This is stargazing in the tropics — on the beach, in shorts and sandals.

Here’s some of our eclipse chasing group enjoying a view of the southern hemisphere night sky, albeit though clouds. Jupiter is the bright object at left, Orion is rising on his side in the middle, Sirius is just above our stargazers, while Canopus is at far right. The Pleiades is at far left. We’re looking east, from a latitude of 16° south of the equator, where the sky takes on a completely new appearance that baffles and delights even seasoned northern stargazers.

Star Party Sunset in the Badlands


A hundred or so stargazers were treated to a beautiful sunset in the badlands of the Red Deer River valley on Saturday night.

This was the setting for the annual Alberta Star Party, at a campground north of Drumheller, Alberta, amid the late Cretaceous sediments of the badlands. This is big sky country.

Earlier in the week the night sky was clear and inviting. But this night the clouds served only to provide a fine sunset. They failed to disappear after nightfall. However, on a such a night, a good time is still had by all as everyone enjoys the company of fellow stargazers during the last of the fine weather before star party season ends for another year.

I took this 360° panorama with a handheld camera, and stitched the segments in Adobe Photoshop CS6.
