Totally agree Paul. I have used home made dew shields on my 4SE MAK and my C5 with no dew issues at all. With my 9.25 it’s a completely different story. I have a Celestron dew shield for it and it’s only really good as a light shield. With such a large piece of glass in the corrector it’s no surprise. My Newts on the other hand I’ve had major issues with the filter on the end of my camera dewing up in the focuser tube. I’ve addressed this with a small dewstrap around the focuser.
