A certain amount of water vapor exists in the air. In the desert, high altitudes or near the polar regions, it can be near zero to as much as thirty in warm, moist or tropical regions. When air begins to cool, it loses its capacity to hold moisture and condensation begins to form. In a high humidity situation, the dew point is reached at a higher temperature and condensation on optics will stop you from enjoying an observing night or a photography session. Nothing is immune and moisture on eyepieces, finderscopes, corrector plates and even primary mirrors not only stops you from viewing, but can add unnecessary dirt on delicate coated surfaces.
We offer many dew solutions for your telescope's dew protection needs. Check out our full line of dew heating systems for your telescope. In this category you'll find dew heater straps, dew heater system accessories, dew system controllers and temperature and humidity sensors. A flexible dew shield for your telescope will offer a very economical solution to your dew problems. A dew cap is a tube, of approximately the same diameter as your telescope tube, designed to fit on the front end of the telescope to reduce the amount of dew that builds up on the corrector plate. It also serves as a lens shade by preventing stray light from falling on the corrector plate, which greatly improves contrast. A flexible dew shield mounts on the front of your telescope tube body and helps prevent ambient dew from forming by recessing the primary lens or corrector plate. Working on the same principle, hard dew shields are constructed from aluminum. Although they are a bit more expensive, they are less likely to get bent or kinked when being transported or stored. Another bonus to the hard dew shield is the dew shield cap . Like the dust cap provided with your telescope, the dew shield cap snaps perfectly into place onto your dew shield itself. This means less time balancing your telescope when you'd rather just leave the dew shield in place and want to protect your lens or corrector plate.
