Quote:I am curious to hear from people who have experienced dew formation on the inside of their SCT, particularly Celestron Edge HD models. I have heard from a couple of people down south in areas like Florida where the dew can be very bad this time of year. They have reported difficulties with dewing on both the outside and inside of the corrector even when using a dew heater. Dew did not appear to be a problem on the primary.Have others run into this? If so, where are you and what are your conditions like?Thanks,Ed.

Quote:Hi Ed, I've noticed this on my 11" Edge HD, but the problem only cropped up on exceptionally wet nights and only when I had my cooling fans turned on. For the record I'm in Houston.
