When the Perseid metoer shower came through back in August I sat outside on the barren hilltop alone from like midnight till 3am taking interval shots of the sky, in hopes of capturing meteors, or at least I could make a composite star trails shot.
Anyway, I was taking 25sec exposures one after another for over three hours. About 40mins in a heavy layer of dew settled on the camera and lens and I didn't even notice. Hours of time, hundreds of shots completely wasted.
Pic is the only one that actually had a meteor in it and it was when the dew was beginning to obscure the lens.
