This is an Astromania USB dew heater strap for 4" scopes in excellent condition. The velcro strap is stretchy, so this will fit around 5" scopes as well, but will not give complete dew removing coverage. In other words, with a 5" scope, there is a gap; the heated element will only cover about 3/4 of the circumference on a 5" scope.
