Spicewood Golf Course, Austin, Texas, 2015-09-14 8:25 PM CDT. Last night’s low humidity was a great chance to capture a sharp image of a day and a half old crescent Moon - only 2.7% illuminated. I took frames of the Moon sinking behind the tree and then after it was out of sight I got better focused and exposed shots of the tree. I liked this image with my best Moon frame, but the overnight 8 parameter affine stacking gives the sharpest crescent Moon image that I’ve been able to take. Questar 3.5 with Sony NEX-5N at prime focus. Moon exposure 0.5 sec and trees 1.3 sec at ISO 800. 33 Moon frames stacked with 8 parameter affine transforms in Nebulosity, deconvolved in Lynkeos, stacked with in focus tree image and final tweaks in Photoshop.
