Did you give your telescope time to adjust to outside conditions?
If you had it in your house where it was cool or warm depending on the
season, then brought it outside where the temperature might be
radically different, you can fog up your lens quite fast. It is not a
serious problem and it will go away, but you need to sit your telescope
outside for a time to adjust to the climate.
