Telescope Warm Up and CondensationPosted By Peter Petrone III |
I have read that bagging or covering the corrector plate on an SCT or lens on a refractor (while still outside) can prevent moisture from forming as the scope warms up inside after a viewing session. Since the thermal mass of the scope is large compared with the volume of the trapped air inside the bag, I do not see this working well. The theory is that the cooler air will act as a buffer allowing the scope to gradually warm up, thus preventing the moisture from forming on the optics. Any thoughts?
