My uncle said to always shoot the moon with a low ISO, and he was totally wrong

He insisted 100 ISO was the only way to avoid grain, but my shots were always blurry from the long exposure. I tried 800 ISO with my DSLR last month and finally got a sharp, detailed crater shot. What's the highest ISO you've used successfully for planetary shots?

Crank that ISO up to 3200 and let your camera's noise reduction clean it up later.

Exactly! Grainy detail is still detail you can work with. Noise reduction software is crazy good now, so you can always clean up a sharp, noisy shot later. A blurry photo just gives you less of everything to start with.

Pushed my old camera to 1600 ISO for Jupiter last year. Your uncle's advice works for a bright, static moon but falls apart on dimmer planets. Modern sensors handle noise way better than the film he probably learned on. A sharp, slightly grainy shot beats a blurry "clean" one every time. Why chase perfect noise levels if the subject is a smudge?
