شريط تدفئة ندى AstroZap لتلسكوبات 3" - AZ703

The 12-inch length wraps my 3" scope perfectly, snug enough that it doesn't slide around even when I'm adjusting the focuser. Fired it up on a damp night and the lens stayed crystal-clear for four straight hours of viewing.

I had a dew problem on my 3” scope until this strap started working—now no more fogging up during long winter sessions. It’s nice that it’s made in the USA and the 12” length wraps snugly without being bulky.

The strap’s 12-inch length fits my scope perfectly, and the even heat keeps the lens completely clear even in damp conditions. Made in the USA, it feels solidly built and plugs in without any fuss.
