I opened for a few short stretches, pushing the humidity limit because the telescope was warm, closing when the secondary got cold, and then reopening after the secondary had warmed again a bit. I didn't run the fans so all focus values were high and seeing was generally poor. We used an eyepiece during evening twilight and then managed to get small amounts of science data later.
