Thanks Monte. I will be mounting the heater strips
inside the Dew Shields in front of the Objective lenses.
There is plenty of room between the Dew shield and the light path on both scopes
I will be placing the Nichrome in between layers of Cloth Gaffer tape, and attaching the whole assembly with sticky-backed Velcro tape
P.S. All that Ohms talk means nothing to me. As soon as I saw all the Mathematical stuff on the sites I closed them
I'll work out the length by feeling how warm the wire gets using Lauries method with a crocodile clip
