Imaged from mountains in central Colorado. Technical. This image was obtained with a Canon 7D Mark II 20-megapixel digital camera and 300 mm f/2.8 L IS II lens at f/2.8 and ISO 1600. No dark frame subtraction, no flat fields. Tracking with an Astrotrac and no guiding. The total exposure was 29 minutes (twenty nine 60-second exposures) plus another 8.5 minutes of exposure (17 30-second

exposures) with the 300 mm plus 1.4x TC (420 mm f/4) for the brighter parts of M97 and M108 to show finer detail. More info at:
