Thanks Phil...looks like they haven't tackled that problem yet.
The DEC ring gear is facing the sky and gets dew accumulation. The water accumulates in the ring gear housing and has no way to drain. The risk is if this water ends up corroding the encoder surfaces and the encoders become unreliable. I've made a plastic cover for my EQ8 DEC axis that seems to be working so far.
The RA axis is a bit less exposed due to the geometry however it is a shame they are including very expensive encoders on that axis and not providing weather shielding.
