We had our windows washed the other day.

Amazing what you can see without opening them.

Clean or not, you need excellent quality to get decent photographs through a window. The optical degradation is proportional to the diameter of the lens. The pupil of an eye being small, unaided vision isn't much impaired. (That goes for binoculars and telescopes, too.)

clarification:
The degradation due to ordinary window glass goes for binoculars and telescopes, too.
