On sat/sun night whilst out observing/imaging I had the worst dew conditions so far this winter , dragon breath visible during dusk and moisture everywhere especially on vinyl sets {damn wet butt}. It was the best test of my Kendricks dew controller and heating straps and the 35amp battery that powers it. It worked well , from previous experiance i knew i had at least 7hrs with 2-3 straps running at near full strength , to conserve energy {had intent to go well after midnight] i ran just two straps for the scopes . The whole night i had no moisture on the OTAs but everything else like the telrad/finderscope/diagonals were dripping.How is everyone dealing with this menace this winter
