Flexible dew shield for Celestron Nexstar Telescope Telescopes

Flexible dew shield for Celestron Nexstar Telescope, close cell foam rubber- advantage

Flexible dew shield for Celestron Nexstar Telescope by ATOZstars is made of black close cell foam rubber material which is oil resistant, ozone resistant and fire retardant. Flexible dew shield for Celestron Nexstar Telescope by ATOZstars will maintain temperature much long than dew shield made with hard plastic because the close cell foam rubber sheet is a very good insulator.
Flexible dew shield for Celestron Nexstar Telescope by ATOZstars has non-reflective flat black matt surface which is essential to eliminate glare cause by stray light. Flexible dew shield for Celestron Nexstar Telescope by ATOZstars uses close cell foam rubber material, 3/16" thick, light weight, yet firm and rigid to maintain cylindrical shape.

Flexible dew shield for Celestron Nexstar Telescope, ABS plastic sheeting-disadvantage

Flexible dew shield for Celestron Nexstar Telescope that is made of flexible ABS plastics sheeting has many disadvantage. This type of Flexible dew shield for Celestron Nexstar Telescope works well except that it is difficult to store. . Flexible dew shield for Celestron Nexstar Telescopes that is made of plastic sheeting can be lay flat when not in use. However, it is too long laying flat. Plastic sheeting Flexible dew shield for Celestron Nexstar Telescope are also too bulking when rolled up. It will not fit in my telescope hard case. There is no good way to store this type of Flexible dew shield for Celestron Nexstar Telescopes. Lastly, the edge of the dew shield come apart when these type of dew shield is roll up tight.

Flexible dew shield for Celestron Nexstar Telescope that is make of plastic sheeting may not have a matt interior surface and would reflex stray light. A reflective surface of the plastic sheeting Flexible dew shield for Celestron Nexstar Telescope would totally defeat the purpose of have a dew shield shield. This property is especially important if the Flexible dew shield for Celestron Nexstar Telescope is to be use as a lens shade.

How dew forms?
When air temperature drop to a certain point at which moisture in the air condense on cool surface. The temperature when dew start forming is called the dew point. The condensed moisture as water droplet is dew. Dew is what prevents you from enjoying star gazing with you telescope at cold nights. As long as the temperature is below dew point, dew will continue to form on your telescope no matter how often you wipe the telescope.

How does Dew Shield Work?
Dew Shield traps stagnated air in the front of the telescope. The temperature of the stagnate air is slightly higher and prevents dew from forming. This slight different in temperature is enough to stop the dew from forming. The insulating property of the dew shield becomes important because it can maintain the temperature longer.

Dew shield can also be use as a lens shade to blocks stray light from entering the telescope. Stray light lowers the contrast of the viewing image. This is especially obvious and important in daylight torrential viewing.

Flexible dew shield for Celestron Nexstar Telescope for Meade Telescopes & Celestron Telescopes
Flexible dew shield for Celestron Nexstar Telescope with flat black surface You need a flat black non-reflective surface
This is a light reflection and glare comparision of the interior surface of our dew shield and other flexible ABS dew shield.

The flat black surface on the right is our dew shield. No reflection, no glare.

The shinny, reflective surface on the left is a flexible ABS plastic dew shield. Lot of reflection and glare.
Flexible dew shield for Celestron Nexstar Telescope Roll up tight for easy storage Roll up tight for easy storage
Our Flexible dew shield for Celestron Nexstar Telescope can be roll up tightly for easy storage.

Other dew shield that is made of flexible ABS plastic can not be rolled up tight and would cause the edge to come apart!
