Getting to look up at the sky tonight and see this:
And you can look all you want, for free!
Also while I am aware I did not discover the moon, a zoom that lets me see the craters on its surface, while not a thrift bargain, makes me feel like an explorer making a new discovery every time! There's not much I don't mind spending real, full-price money on, but I do not regret my camera. Not one bit.
