- the camera was not removed or disturbed from the prior 2.5hr run on 3132, so no way ANYTHING got in there.
As I mentioned WAAAAAAAAAY back in post No1 (I think), the temp SUDDENLY dropped to 5.7° (was 8°, and that is why I rechecked focus), so I suspect the front that came through was happening just then and I was getting pre-frontal atmospheric disturbance/ice/vapor...
The SBIG cooler percentage was 78% prior to this change, and during the change, it dropped to 54% cooling - so, the cooler atmosphere was aiding and abetting the cooling.
If anything it's a bad advertisement for SBIG
Anyway, another EP size dew strip on the way to preheat the camera nosecone...
