C/2025 A6 (Lemmon) captured with my usual and modest astromodified a7III at 600mm. By pure chance, I was able to try the Sony 200-600mm a couple of nights ago. My intention was to make a few tests, to shoot Andromeda, Orion, and the Pleiades just to see how they look at 600mm, and I thought of giving the comet a try. I was shocked when I saw it on the camera, and after a while of trial and error, I was able to stack 23 shots—not much more than one hour of integration. For me, it’s the first time I’ve shot and finished a photo at this focal length, and this comet was a great experience to start with.
