<p><em><span style="color:#999999;">The autumn stars rise in trails over Athabasca Falls and Mt. Kerkeslin in Jasper National Park.</span></em></p>
<p>Last night was a good one for shooting nightscapes in Jasper. Skies cleared for a beautiful moonlit night, ideal for nightscape shooting.</p>
<p>I went to Athabasca Falls, a popular scenic attraction in Jasper but deserted after dark. I set up cameras at the usual overlook, shooting both a time-lapse and star trail set.</p>
<p>The main image above is the result of stacking 100 images in the star trail set. I used the <span style="color:#3366ff;"><a style="color:#3366ff;" title="Star Circle Academy blog" href="http://starcircleacademy.com" target="_blank">Advanced Stacker Plus actions</a></span> from Star Circle Academy.</p>
<p>The foreground comes from one image, shot early in the sequence when the Moon lit more of the landscape. The Falls themselves remained in shadow, as I had expected from my lighting angle calculation and knowing the site.</p>
<p>The star trail image shows the autumn stars of Andromeda, Cassiopeia ad Perseus rising over Mt. Kerkeslin, the famous backdrop to Athabasca Falls on the Athabasca River, making its way to the Arctic Ocean</p>

<p>This image is a 4-segment panorama I shot earlier in the evening in the twilight, with the waxing Moon over the Athabasca River.</p>
<p>In the early 1800s, after explorer, astronomer, and fur trader David Thompson had to abandon his original route over the Rockies at <span style="color:#3366ff;"><a style="color:#3366ff;" title="Sunset over David Thompson Country" href="http://amazingsky.net/2014/08/14/sunset-over-david-thompson-country/" target="_blank">Howse Pass</a></span>, he came north, and followed the Athabasca and Whirlpool Rivers up over the Athabasca Pass, his new main route to the B.C. interior.</p>
