Unfortunately, I saw the same problem a couple of days later. See attached. The corrector plate on the CCD started to cloud from the start. Took it off the scope and indoors to sit nosepiece down on a radiator for an hour…. Not an ideal way to treat kit, but with the first clear night in weeks and no moon I really didn’t want to waste more time than I had already.

Later that night there were also hints of condensation inside the corrector plate – so, dew shield now on order. May have to wait ’til a low humidity day and get some air moving through the tube while its in the sun. So, realistically first chance in April?
