Adaptive
AFAIK adaptive optics involve an artificial guidestar (laserbeam), the fuziness of which is in direct relation to the 'adaptive' part of adaptive optics, which in turn involves a sectioned mirror where single sections can be moved to "adapt".
(I'm wondering who'd be so sad to "enhance" his webcam in that way...)
On a completely unrelated note, I lost count of how many times I read about some boffins pleading to not use the word boffin here on ElReg. Dear boffins, please stop that, it is not funny anymore and it won't happen...
Btw, light years are soooo yesteryear. Use sheep years instead...
