Hi
Is this normal.
On seeing these gently cleaned it after blowing away any dust and then gently cleaning with a lens
cleaner!
Pls advise
Looks to me like condensation formed on the inside of the lens and after drying up left a watermark on the lens.
If you take the projector from a cold place to a warm and humid place this might happen, normally the condensation would evaporate slowly and not leave any marks but somehow the conditions you use it in are such that this happens.
I however believe that it will have very little to no effect on the projected image quality

You could experience the same indoors if the temperature and especially humidity vary wildly.
