We noticed last night that the allsky camera dome was fuzzy and foggy. Going outside we found the inside of the dome condensing and freezing in places. The 24vdc heaters were working but the 12vdc circulation fan had failed.
This will push up the redesign of the dome system to this weekend I think. Adding two circulation fans and mounting the heaters up off the wood and bringing the camera body up higher into the dome as on the list of modifications.
