Sure, it’s a moon I captured on a slightly hazy night, but I wanted to really test out my tripod and telephoto lens and capture something my cell phone would just repeatedly fail at. Ended up going with a one-second shutter after a two-second timer so my hand wouldn’t mess with the tripod balance, and with ISO 100, I had a long enough window to capture good detail on the moon, at least as much as my 75-300m f/4-5.6 telephoto lens would allow. There’s bigger lenses that do more daring stuff, but this one is mine.

Thanks for seeing some really big sky cheese!

Ooooh.

(I do have to take my tripod with me, as I have some substantial physical difficulties and can’t even use a regular telephoto lens without a tripod. Turns out, I’m not stable. Don’t have strokes, kids.)

I should really try a high stop value for aperture for my next moonshot!

You don't necessarily have to stop your aperture down that far, but I suspect you should be able to use a much shorter shutter time. That'll cut down your overexposure and possibly also help with the color fringing around the edges.

There will be a sweet spot of aperture for your lens where the sharpness and chromatic aberration (color fringing) are at their minimum. This is unlikely to be at the extreme open end (low ƒ number) or far down into the extreme closed end (high ƒ number). You can experiment to find where this is for your particular lens, though. The beauty of shooting digital is that film is free and you can review your results right away.

ƒ-16 was probably actually too small an aperture for my shot, but it worked well enough.
