Yes, I concur. I have an 8" SCT and operate in sub-alpine conditions. You will need both! It gets very frustrating otherwise. I also frequently use a 12V hair dryer to give the heater and dew shield the occasional boost when required! I find the dew/frost can start to appear from your secondary out even with the dew shield and heater on, so at the first sign of loss of contrast, check your corrector.
The only other advice I have is to avoid rain (it's just heavy dew really!!!
)
