Astrozap 5インチ望遠鏡用デューヒーターストリップ - AZ705

I’ve been using this 17-inch strap on my 5" telescope for a few weeks now, and it’s completely stopped fogging up the lens even on humid nights. The build quality feels solid, and it heats evenly across the whole surface.

Finally—no more wiping fog off the eyepiece after ten minutes outside. This strap’s 17-inch length wraps my 5-inch scope perfectly, and the material feels sturdy enough for regular winter nights.

The adhesive holds snugly against the tube all night, and the 17-inch strip covers the full aperture without any sagging. I’ve used it three nights straight with zero fog buildup, which is exactly what I needed for my scope.
