AstroZap Binoview Heater (Pair) - AZ-718

After months of fogging issues with my binoviewer, these bands fit snugly and the even heat generation across the full band length finally solved it. Nice to see the side that rests against the telescope stays just as warm as the rest.

The even heat distribution across the band is a game changer for my binoviewers, and it fits snugly without any loose spots. I was able to stay out for hours without a hint of fogging, which made my observing session much more productive.

Wrapped these around my binoviewers on a damp night and the even heat kept the optics completely clear for a solid three hours. The bands sit snug without squeezing the tubes, which is exactly what I wanted.
