AstroZap dauwverwarmer voor Telrad - AZ-721

After a few sessions with frost forming on my Telrad, this band wraps snugly and generates heat evenly across the whole length, keeping the view crystal clear. It's simple to install and makes a real difference on humid nights.

Finally, a heater band that actually stays snug against the finder scope and doesn't need constant re-taping. No more dew ruining my alignment halfway through a session. The even heat across the whole band is a game changer.

I was worried about fogging on chilly nights, but this heater band cinches snugly around the finder and keeps it crystal clear. The heat really does spread evenly along the whole band, which made a noticeable difference during a humid session.
