Used Generic Dew Heater Strap for 2" eyepieces/50-60mm scopes Nikon and includes a cardboard BahtinovThis is a generic dew heater strap for 2" eyepieces and 50 60mm scopes that is in excellent condition. The velcro strap is stretchy, so this will fit around 60mm scopes as well (we have tested this in the store), but will not give complete dew removing coverage. In other words, with a 60mm scope, there is a gap; the heated element will only cover about 3 4 of the circumference on a 60mm scope. You will need a dew heater controller with RCA plugs for
