Omegon Heater Strap 9" (100cm)
Omegon heating strips keep off the dew and guarantee you super clear observing all night long. 100cm designed for 9" OTA
Heating strips - keeping your view of the night sky clear
Nights are not always as dry and clear as you would like. Optical surfaces will often fog up at night. And once your optics - eyepieces, lenses or Schmidt corrector plates - have fogged up, then your observing is over for the night. But this can be avoided.
The advantages in a nutshell
- heating strips stop your telescope, finder and eyepieces from fogging up.
- easy adjustment - a flexible strip for a perfect fit
- adhesive strap - holds fast at any point on top of the heating strip
- cinch connector with 2 metre cable
- available in different lengths
Compact and can be used at any time
Highly practical - at the beginning of your observing session, simply wrap the heating strip around the OTA or your eyepiece. The strip fits like a glove and can be fixed in place using the adhesive strap fastener. After you are finished observing, just stow it back in the eyepiece case. Your telescope heater for ensuring your optics remain fog-free will hence always be handy.
Keeps your optics free from fogging-up
Connect the one metre cinch plug cable to a suitable power source. A 12V DC supply distributes the energy evenly to the strip, at only 0.2 watts per centimetre. This means the heating strip maintains the temperature effectively a few degrees above the outside temperature, so dew now has no chance to form. Also, it only needs minimal energy and is therefore gentle on your battery.
The heating strip can be connected to a pulse controller, allowing it to be operated in a power-saving mode. Tip: We recommend the Omegon control unit for your dew heaters. This allows you to connect up to two heating strips at the same time and individually adjust the power to each one.
Why do your optics fog-up?
The effect of dew on an optical surface is well known to every spectacle wearer who has come into a warm room from cold conditions outside - a fine mist of water droplets forms on the spectacles as the warm air condenses onto the cold glass surfaces. Exactly the same happens on the lenses of your telescope optics. As your optics cool down, water condenses onto the surface. Then it's time to free your view!
Omegon heating strips offer you longer, and more pleasurable, observing sessions. When other astronomers have already packed up their telescopes and left, you can stay observing for as long as you want!
