Subject:
TWP/TSI/C1 - hazy image
DataStreams:twptsiskycoverC1.b1, twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskyimageC1.a1
Description:
When the TSI from Darwin was installed (so the instrument from Manus could be returned to 
Darwin for repair) moisture in the camera lens and filter caused the sky image to be very 
"hazy". The U10 chip was removed from the control board, desiccant was installed inside 
the enclosure, additional small desiccant bags were installed inside the camera housing, 
the camera housing was sealed with silicon to prevent moisture ingress, and the camera 
lens filter was cleaned and the focus adjusted.
