Fuzzy telescope??

[Westgaterose]

Hi again

Can anyone tell me why everything I look at through my telescope this evening is all fuzzy? Almost like looking through one of those kids toys where you look through the tube and turn the end to get funny crystal shapes. It didn't matter which eyepiece I tried. I moved the focus from one end to the other but the fuzzy light refused to coalesce into a planet.

Bit gutted as Mars was twinkling at me tonight.

Many thanks

Could be either dew or frost on your objective, that would pretty much make everything fuzzy.

Sounds like frozen optics.

If your eyepieces get very cold they can mist up when you try and look through them - the heat of your eyeball is enough to do this. Try keeping your eyepieces slightly warmer than the outside temp.
