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.
