Dewing of a mirror or object glass can be countered with various devices
and methods, but its occurrence inside a closed system is particularly
problematic. I have received the following enquiry (from an experienced
observer who has used several instruments over many years) concerning
dew on a corrector plate, and would be pleased to hear from anyone who
who has a remedy:
'Having recently obtained an 8-inch Meade SCT I have been having serious
problems with condensation, which persistently accumulates on the inside
of the corrector plate. I have fitted a dew shield and tried a heater,
but these have been only partially successful in limiting and/or
delaying the inevitable.'
