    Default Great night bad night



    Had great clear skies in scotland last night started with saturn wich was looking great then just some random searching and found M3 star cluster and then found M56 planet nebula which was very very faint then it al went wrong couldnt understand why it was down to dew gathering on my scope couldnt see through my finder scope at all and was very blury through the eyepiece so had to accept defeat and pack up after about 2 hours hope some one can advise me on how to avoid dew on my scope many thanks

    Scopes like to dew up. A blast form a small portable hair dryer usually does the trick. You can also buy a product like dew heaters/dew zappers. They wrap around various parts on the scope to keep it from dewing up.
