As the sun was getting ready to set over Lake Michigan tonight, I turned to the southeast and noticed the giant moon in the blue sky overhead. Luckily, I already had my giant 600mm F4 lens out and on the tripod. I pulled the 1.4 extender out of my bag and attached it between my camera body and the end of my lens to help zoom in on the vibrant moon even more. F5.6 at 1/1000, ISO 400, 600mm lens at 840mm
