-4.3 Magnitude Venus Shines at f/11

I was getting ready for the ISS pass last night, and I couldn't resist getting a quick shot of Venus blazing at magnitude -4.3 to the SW. I didn't realize it at the time, but I left my camera settings stopped down from a previous moon photo, and was shooting at f/11. Smaller apertures (higher f-stop numbers) can produce sharper images but let in less light. They also seem to create these starburst patterns around bright lights.
