Went out on a rare clear night to a wetlands near me to take some photos of the stars. As it was so dark, and the stars are so small, I had to rely on the focus peaking function of my camera to tell if the stars were in focus or not.
I’ve got home and started to process the photos, and I’ve found out that despite the camera telling me that they were in focus, they clearly weren’t.
Hey ho, what’s a wasted few hours in the freezing cold between friends…
On a good number of newer automatic lenses going all the way out will take you past infinite. Best to zoom in on a bright target star, I usually use live view and zoom in on the display as well. Focus on that star and don’t touch the focus the rest of the night.
