Howdy all; Well, after the dew bath at Sentinel last new moon I decided to get a dew heater for the SCT. I have not used it, but I bought the one from scopestuff dot com. It was about half the price of the Kendrick system. It is a heating strip for the front element of the C 11 and another for the eyepiece. I am guessing that I can use it for the 4 inch refractor if I take that out. I would just wrap the heater strip around the dew shield of the refractor several times. That is my plan; I will let you know how it turns out as time goes by. Clear Skies to us all; Steve Coe P.S. I am planning for a trip to Sentinel for February, I hope that I will not need the new gizmo..well shall see. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
