Do the dew

  1. Mar 19, 2010 #1
    So, I just received my 3x barlow lens in the mail and let my scope sit outside for two hours to adjust..later I realize the humidity is 80-90% and my scope (6" dob) is literally dripping. Other than moving to Arizona, is there a practical solution to this problem?

    Not really, no. All you can do is try to keep dew off the mirror (which for a dob shouldn't be much of an issue). Dew on the tube really isn't going to hurt anything.
