I have seen the pictures it takes but how?
It’s basically an electronic CCD, just like any digital camera.
Maintaining the guiding accurate to a fraction of an arcsecond is done using feedback — by observing fairly bright stars near the field being observed, and nudging the pointing with gyroscopes.

Good question, and to whomever answers, how does it remain aimed so precisely to within a fraction of an arcsecond? Do the electonic imagers adjust for this or does the whole spacecraft remain that steady?

It uses radiowaves

just like Austin Powers does… with a camera. Of course the Hubble doesn’t have to inspire its models like Austin:
"You’re an animal. You’re a tiger. Be a tiger, baby! You’re great! You’re Grrrrrr-eat! You’re Tony, be corn flakes"
