dew?

[Steve_meg]

Hi all

I just speant the last few hours view the sky. but when i packed away my scope there was a small film of dew on its outside. when brought inside i could see a small amount on the two mirrors. is there anything i need to do or will this just evaporate??

Just let it evaporate and it will be as good as new in the morning. Wiping it off with a cloth risks scratching the mirrors and any residue left behind by the water droplets won't affect performance noticeably, if at all.

Dont worry i was way to scared to touch the mirrors. I though it would evaporate ok, just wonder if people leave there dust caps off or some other trick.

You can zap it off with a hair-dryer.

When you come in remove all the Caps and stand the tube facing down. This will prevent the dew running down on to the mirror. leave the caps off over night and by the morning all will be OK. There very few reasons for cleaning the mirrors..........they can build up a lot of dust and the viewing will not be affected
