I could not have asked for a more perfect night for a lunar eclipse. It doesn’t get any better!
On Sunday, September 27, the Moon was eclipsed for the fourth time in two years, the last in a “tetrad” of total lunar eclipses that we’ve enjoyed at six-month intervals since April 2014. This was the best one by far.
The timing was perfect for me in Alberta, with the Moon rising in partial eclipse (above), itself a fine photogenic site.
In the top image you can see the rising Moon embedded in the blue band of Earth’s shadow on our atmosphere, and also entering Earth’s shadow on its lunar disk. This was a perfect alignment, as lunar eclipses must be.
For my earthly location I drove south to near the Montana border, to a favourite location, Writing-on-Stone Provincial Park, to view the eclipse over the sandstone formations of the Milk River.
The image below shows a screen shot of my site plan and viewing angles using The Photographer’s Ephemeris app.
More importantly, weather forecasts for the area called for perfectly clear skies, a relief from the clouds forecast – and which did materialize – at home to the north, and would have been a frustration to say the least. Better to drive 3 hours!
This was the second lunar eclipse I viewed from Writing-on-Stone, having chased clear skies to here in the middle of the night for the October 8, 2014 eclipse.
I shot with three cameras: one doing a time-lapse through the telescope, one doing a wide-angle time-lapse of the Moon rising, and the third for long-exposure tracked shots during totality, of the Moon and Milky Way.
That image is above. It shows the eclipsed Moon at left, with the Milky Way at right, over the Milk River valley and with the Sweetgrass Hills in the distance.
The sky was dark only during the time of totality. As the Moon emerged from Earth’s shadow the sky and landscape lit up again, a wonderful feature of lunar eclipses.
While in the above shot I did layer in a short exposure of the eclipsed Moon into the long exposure of the sky, it is still to accurate scale, unlike many dubious eclipse images I see where giant moons have been pasted into photos, sometimes at least in the right place, but often not.
Lunar eclipses bring out the worst in Photoshop techniques.
Above is a single closeup image taken through the telescope at mid-totality. I exposed for 8 seconds to bring out the colours of the shadow and the background stars, as faint as they were with the Moon in star-poor Pisces.
I shot a couple of thousand frames and processing of those into time-lapses will take a while longer, in particular registering and aligning the 700 I shot at 15-second intervals through the telescope. They show the Moon entering, passing through, then exiting the umbra, while it moves against the background stars.
So I was a happy eclipse chaser! I managed to see all four of the lunar eclipses in the current tetrad, two from Alberta, one from Australia, and one from Monument Valley.
With the latest success, I’ve had my fill of lunar eclipses for a while. Good thing, as the next one is not until January 31, 2018, before dawn in the dead of winter.
With the mild night, great setting, and crystal clear skies, this “supermoon” eclipse could not have been better. It was a super eclipse.
