Update
This is a bit of an update. Its been 7 months since this work was undertaken. Thus far the camera is working well and does not seem to have any corrosion present. Happily it appears the conformal coating has worked.
The camera has undertaken many imaging runs with seven objects imaged or in the process of being imaged. There was one night when I got a strange set of prison bars at the very end of the night on one image. I suspect this was a power outage and the UPS was not able to deliver all the power the camera needed. The dome was open in the morning too and this would seem to confirm a power outage. In any event, the artefacts have not been seen since.
I'll report again in 6 months with how the camera is operating. Fingers crossed. If I get past 12 months then I will have confirmed that the problem was a design fault and that perhaps it ought to be looked at for future designs. Time will tell.
