<p><span style="color:#cc99ff;"><em>The annual Dark Sky Festival in Jasper National Park ended with the best finale – dark skies, on a beautiful star-filled night. </em></span></p>
<p>On Saturday night, October 22, I left the final set of science talks in the Big Tent at the heart of the Festival and headed out down the Icefields Parkway for a night of shooting Jasper by starlight.</p>
<p>The lead image is of the winter stars, including the Pleiades, rising above Mt. Kerkeslin at Athabasca Falls.</p>

<p>I shot the image above moments later, from the usual viewpoint overlooking the Falls, reduced to a trickle in late autumn. Illumination is solely by starlight – no artificial and glaring light painting here.</p>

<p>At the start of the night I stopped at the viewpoint for Athabasca Pass far in the distance. The summer Milky Way was setting over the pass. This historic pass was used by David Thompson in the late 1700s and early 1800s as his route into B.C. to extend the fur trade across the Divide. Thompson writes in his Journal about one particularly clear night on the pass:</p>
<p><em>“My men were not at their ease, yet when night came they admired the brilliancy of the Stars, and as one of them said, he thought he could almost touch them with his hand.” </em></p>
<p>The night ended with a display of Northern Lights over the Athabasca River. What a superb night under the stars in Jasper!</p>

I shot this from an access point to the Athabasca River by the bridge on Highway 93 on the Icefields Parkway. Pyramid Mountain is at left near the town of Jasper. Vega is the bright star at left; the Big Dipper is at right.\r\rThe image is a stack of 10 exposures for the ground, mean combined to smooth noise and to smooth the water, and one exposure for the sky and aurora. All 15 seconds at ISO 1600 at f2 with the Sigma 20mm lens and Nikon D750.&quot;,&quot;created_timestamp&quot;:&quot;1477209678&quot;,&quot;copyright&quot;:&quot;\u00a9 2016 Alan Dyer&quot;,&quot;focal_length&quot;:&quot;20&quot;,&quot;iso&quot;:&quot;1600&quot;,&quot;shutter_speed&quot;:&quot;15&quot;,&quot;title&quot;:&quot;Aurora over Athabasca River&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="Aurora over Athabasca River" data-image-description="" data-image-caption="&lt;p&gt;The Northern Lights over the Athabasca River in Jasper National Park, Alberta, Canada, on October 22/23 at about 1:30 am.

<p>As a finale, here&#8217;s a music video collecting together still images and time-lapse movies shot this night, and on two other nights during the Dark Sky Festival, including at the big Lake Annette &#8220;Beyond the Stars&#8221; star party I spoke at.</p>
<p>Enjoy!</p>
