Beginners Mistakes Continued..

Well the other night viewing I must have left the focuser uncovered for to long and moisture got in the OTA and the primary dewd up , which I understand is not supposed to happen with a closed assembly. I just noticed I have some dew residue on the primary that reflects an awful lot like the dew pattern I noticed on it the other evening. Does this mean I have to clean my primary or will it be negligible??

I don't even want to think about taking that thing apart. I'm not sure if it will be easy or hard.

Chris: You shouldn't take it apart. Just leave it open in a warm, dry, dust free place and it will evaporate.

You must make certain that it is completely dry inside. If there are spider web type patterns, that can indicate the growth or mildew or mold. If that is true, then this must be removed or it will etch the coatings when the mildew grows. A pattern of dots or small circles would just be residue from the dew. I cannot tell you how to be sure without seeing it or disassembly.
