Front glass fog from the inside.

There is air inside those lenses and if you go from one extreme to another temp wise you can have moisture condense on the inside of the lens. Gotta wait for temps to equalize for "fog" to go away.

Hi Luis:
Is it possible that you could describe the problem again?
I'm having difficulty understand exactly what is wrong.
Will try to help if I hear back from you.

Is it fogging up when you use the heat or a/c? Is it fogging up after sitting outside on a particularly dewey night?

An easy fix and one to try first is turning the temperature gauge over toward heat, and setting the directional controls to defrost. Up the power on the blower for a moment. The warmer air will usually clear up a foggy windshield in seconds on a chilly or even not-so-chilly morning. The condensation on the glass needs a change of temp in order to evaporate. Sometimes you can get the same effect by using outside air to circulate through your car's blower system. Most have a way of circulating either inside-car air, or outside-car air.

If the glass fogs when you're driving down the road and have the heat on, or the a/c - do you smell something sweet or see white smoke coming out of your air vents? If so, you could have a faulty heater core. I wouldn't imagine this is the problem on such a new vehicle, but it could still malfunction.

Of course, if you're trying to wipe this fog clean and it won't go away, maybe you've got someone smoking in the car and leaving a film on the glass. It would take a lot of smoking to make the windshield look foggy though.

NEVER EVER disassemble an eyepiece --- no one can tell you how the lenses go together there are dozens of combinations and some eyepieces have as many as 6-8 glass lenses inside!

Sorry buy another eyepiece and only clean the outside surfaces.

Take the printer apart. It's usually less than 8 screws. Clean theback of the glass .... Bingo ..... Also google the Dell model printer. How to take apart a bla bla printer. From. Google.com.

You need to contact Celestron or a Celestron dealer:

It can be cleaned, but I would recommend you see if there is a local astronomy club, whose members can help.

What is happening is, when the scoped hunting firearm is stored inside the night before the hunt and its warm inside the house and when you go outside in the cold, the scope fogs up. Much like someone who wears glasses, when they are inside a warm house and they go out in the cold, their glasses fog up. The way to prevent this is to store the gun outside the night before the hunt where it's still secured but cool like the outside. Lock it in the trunk of your car or a locked tool box in your truck. In this way, the scoped hunting firearm will be about the same temperature as the cool outside air and it will not fog.
　
　
　

clean it with winddex realy good here and there it happens to me too on my daewoo :)

Possible heater core leak. Is your coolant level going down, and perhaps an odour inside? Can you feel a sticky film of inside of windsheild?
