From one of the timelapse sequences from last week’s Comet Pan-STARRS shoot; sequence covers from 2008 to 2026 hours on March 13, 2013, images captured south of Santa Fe, NM using a Canon 5D MkIII with a 70-200/2.8L IS + 1.4x TCII, at 280mm.
I pulled evenly-spaced frames and composited them into a single image, showing the comet’s path down from the cloud to the ground. Key images adjusted for contrast prior to exporting from Adobe Lightroom, and then composited into a single Photoshop file. Laboriously. :)
