TIL that leaving my DSLR on the tripod all night in the backyard was a $200 mistake
I woke up in my yard in Tucson at 5am to find the dew had soaked the whole lens and body after a 7 hour star trail attempt, and after drying it in rice for two days the autofocus is now grinding, so what is everyone using for dew heaters that won't break the bank?
