I don't mind opinions but it is very discouraging to see any post like this one that actively discourage the value of basic physics in favor of "common sense." For anyone with a technical education, "common sense" includes the principles of physics. I'm not going to comment on all of the incorrect points here but I will point out that the 'R' value of any insulator takes into account both conductive insulation and radiative effects. They don't make Reflectix shiny just because it look pretty.
I really don't care what you "don't mind". You don't need a degree in thermodynamics, statistical mechanics, and kinetic theory to understand how to put a blanket on a telescope, professor John. Reflectix is a product that was developed for the construction, and packing industry, not for amateur Astronomy. Though many who possess common sense have learned how to adapt it even without your superior intellect. I didn't "actively discourage" anything, except perhaps, over-thinking. Interestingly, the cave dwellers knew enough to put a "door" on a cave, and to wrap themselves in an animal's pelt with the fur to keep warm. They had no clue what thermal physics were, but yet, they had common sense to see that stopping air flow keeps heat in. Common sense that you seem to be discouraging, unless of course, one has a "technical education". You hijacked the original question and turned the thread into a "superior technical" thread. Do you remember the OP? Here, I'll help...
"I observe in areas that are prone to prolonged heavy dew/frost. If there is no dew/frost, that would be the exception. Unless I put the dew shield on the scope, and wrap warming strips around the OTA behind the corrector, around the eyepiece, on the Telrad and around the finderscope objective and eyepiece, turn on the batteries and keep them on, dew/frost will form on the optics, guaranteed. It's not really a question of if dew/frost will form, but when it will form: sooner or later. The warming strips DO prevent dew/frost.
So if I wrap the OTA in Reflectix, will I still need the warming strips to prevent dew/frost? If there is a choice between no thermals and no dew/frost, I'd rather do without the dew/frost. The effect of dew/frost on the corrector is a lot worse for observing than thermals in the tube.
