Cassiopeia and Cepheus reign over the autumn sky amid the Milky Way.
This is a photo from last night’s shoot, taken on a very clear autumn night with the Milky Way prominent across the sky. I shot sets of constellation images, among them this one framing Queen Cassiopeia and King Cepheus.
Cassiopeia is the well-known “W” pattern at lower left. Cepheus is harder to pick out – he’s a crooked square at right, topped by a tall triangle, like a child’s drawing of a house.
The Milky Way runs across the frame, peppered with red nebulas, from IC 1396 at far right in the bottom of Cepheus, to the NGC 7822 complex at centre, and the IC 1805 complex at far left. Lots of smaller nebulas dot the scene. At far left is the Double Cluster, two adjacent clumps of stars in the outer Perseus Arm of the Milky Way. Most of the deep-sky objects in this frame lie thousands of light years away in the next spiral arm out from the one we live in, or in the space between the two arms.
Most of the bright stars here are young blue stars. But a couple of exceptions stand out: yellow Shedar (or Alpha Cassiopeiae, the bottommost star in the W and an orange giant), and red Mu Cephei, at far right bordering the round IC 1396 nebula. That star is also known as Herschel’s Garnet Star. It is a red supergiant star 1400 times larger than our Sun and one of the most luminous stars in the catalog.

Highway One heads into the setting equinox Sun.
I try for this shot every year, and every year I’m thwarted by low clouds over the Rockies to the west.
So here’s the shot from tonight, Monday, September 23, the night after equinox. Had the horizon been perfectly clear tonight the Sun would have appeared right at the end of the Trans-Canada Highway as it set behind the Rockies. Instead, it disappeared higher up and to the left, behind low cloud.
At equinox (fall or spring) the Sun rises due east and sets due west. So tonight, it was shining into the eyes of all the drivers as they headed west into Calgary – a little demonstration of the annual motion of the Sun.
The previous night, Sunday, Sept. 22, I shot a time-lapse movie of the scene, again hoping for a clear shot to the setting Sun. Alas! A neat movie but still not quite what I was after.
There’s always 2014. But I think I need to aim east and catch the rising Sun at equinox instead. The mountains attract too many clouds.

The Big Dipper swings behind the Hoodoos in the Red Deer River badlands on a moonlit night.
Last night I headed north to the Red Deer River valley to shoot a time-lapse over the river with the badland hills lit by the rising waning Moon. After finishing that I stopped at the popular Hoodoos tourist attraction on Highway 10 east of Drumheller. I had the place to myself at midnight, and the photo ops around the moonlit hoodoos were many.
These formations form when harder capstone rock prevents the soft lower layers from eroding in the rain.
The Big Dipper was nicely positioned above the hills as it swings low across the northern horizon in autumn.
Here I aimed back toward the Moon, with its glare muted by high cloud, and backlighting the hoodoos. The stars of Perseus are rising at left. Unlike normal astrophotography, with nightscape work, and certainly time-lapse shooting, clouds can be a benefit.
This was a great spot to end an evening of nightscape shooting.

The Harvest Moon rises into the dark arc of the Earth’s shadow.
What a perfect night this was. The Full Moon rose into a crystal clear sky, tinted with the dark blue shadow of our planet arching across the eastern sky.
The main image above is a 7-section panorama sweeping from northeast to southeast, but centred on the rising Harvest Moon rising almost due east.
The Moon came up just before the Sun set. The panorama below shows that scene. It’s a crop of a full 360°, 45,000-pixel-wide panorama, taken just as the Sun was setting almost due west and the Moon was rising 180° away in the east.
I took both panoramas with a Canon 5D MkII and 50mm Sigma lens, with the segments at a 30° spacing. That way I take 12 segments to cover a full 360°, a habit leftover from the days of shooting photo pans for planetarium projection systems consisting of 12 Kodak slide projectors.
My previous post showed some still frames from a time-lapse movie of the rising Harvest Moon. The final movie is above, assembled from 670 frames taken at 2-second intervals with the Canon 60Da and 200mm lens. I’ve shot this subject a few times now, but this was my best capture of the rising Full Moon at harvest time, always the most photogenic Moon it seems.
It was a marvellous night for a moonrise!

The Harvest Moon rises with pink hues into the deep blue twilight over prairie fields.
This was the scene tonight, September 19, as the Full Moon rose into a clear eastern sky. The view was perfect, with a cloudless horizon (for a change!) and the Moon prominent and pink as it rose into the twilight sky.
The main image is from a few minutes after moonrise. The bottom image, with a dimmer Moon, is from just after moonrise.
In neither case did I punch up the Moon in contrast or colour separately from the sky to make it stand out more than it did in real life. And I certainly did not paste a telephoto lens shot of the Moon into a wide-angle scene. That’s faking it. This is real.
Both frames are from a 670-frame time-lapse sequence, from the Moon first peaking above the horizon to when it rose out of frame at top right. That’s still in processing!

The Harvest Full Moon sets into a prairie scene lit by the rising Sun.
This was the scene this morning, September 19, as the Full Moon set just after sunrise on a perfectly clear morning.
Clear, of course, but for the only clouds in the sky just where I wanted to shoot. However, in this case they did help make the scene, adding more colours to the western sky at dawn.
This was the true Harvest Moon, as moonset occurred only a couple of hours after the official moment of Full Moon. However, the setting moons of Wednesday night, September 18 and Thursday night, September 19 can both claim to also be the Harvest Moon, the Full Moon closest to the autumnal equinox.
I plan to shoot the Moon coming up again, 12 hours after it set for this photo, and right at sunset tonight.

The Pleiades rises beyond the old farm gate on a moonlit prairie night.
It’s been a wonderful few nights for nightscape photography, with a bright gibbous Moon lighting the golden prairie landscape. Skies have been clear and the nights warm, ideal for 3-hour shoots of old farmsteads and prairie scenes.
I’ve spent the last few nights at the abandoned farm near home, shooting time-lapses. This is from Monday night, and is one frame from a 360-frame dolly-motion time-lapse.
The Pleiades star cluster rises in the east over the old barn and farm gate. A car travels through the coulee, leaving a streak of headlights.
I hope the weather continues, so I can harvest some more images, making time-lapse “hay” while the Moon shines!
