A Crisp Winter’s Night Under the Stars

It was crisp and frosty night filled with the bright stars of winter, and the Milky Way.

This was the sky from my backyard on Thursday, February 7, with Orion and his friends shining due south. It is a “fish-eye” shot taking in all of the sky from horizon to horizon. South is at bottom, north to the top. West is at right, east to the left.

The Milky Way runs from northwest, at top right, to southeast, at bottom left. When we look at this section of the Milky Way we are looking in the direction opposite the galactic core, toward the outer arms of our Galaxy.

Jupiter is the brightest “star” in the image, shining in Taurus. Rising out of the sky glow from towns to the west of me is the pillar of light called the Zodiacal Light. I think you can follow it stretching all the way across the sky from right to left (west to east) where it then becomes a subtle bright patch in the sky well east of the Milky Way. That’s the Gegenschein, a glow of light exactly opposite the Sun. It and the Zodiacal Light are caused by sunlight reflecting off comet dust in the inner solar system.

A night when you can see the Zodiacal Light and Gegenschein – they were visible to the unaided eye – is a good night indeed. Too bad this one was spoiled by some cloud and haze, reflecting the toxic yellow glow of ever-intruding sodium vapour lights.

Silhouetted in the sky glow at right is one of my telescopes, with camera #2 dutifully taking a closeup image of Orion’s Belt. That picture will be the subject of tomorrow’s blog!

Yes, on a good night it’s still excellent, but light pollution is getting worse from development locally and growing Strathmore. I can’t shoot down too low, except on an exceptional night. This night was hazy with frost and it got worse later on, not to mention frost on the lenses. But if I get a couple of shots off on a winter’s night, I’m happy. This is with the Sigma 8mm.
