Why does nobody warn you that dew will eat a whole night of imaging?
I was out at a dark site near Payson last month and my corrector plate fogged over about 40 minutes in, so every sub after that was junk. Grabbed a $12 heated strip from the case I never used and the rest of the night came out clean. Now I'm wondering how many other guys keep a dew heater buried in their bag and never touch it until it bites them.
