Hi, we have received an Edscorp 6" Reflecting Telescope, like this one. There are a couple of issues, the mirror got moisture on it and has black dots on it.
The other issue is the piece that connects the white part with the base is frozen, so how do you get it apart?
Leave the tube open until all moisture dries. Moisture from dew is normal and doesn't do any
real harm. Black dots may be mold. That should be removed by cleaning the mirror. Taking
the mirror out and cleaning it is no big deal. Just make sure to read how to do it correctly. Lots
of info how to do that on this site.
I think what you mean when you say a piece of the scope is frozen is that the clock drive clutch
mechanism has seized up and does not move freely. I had that particular problem with my Edmund 6" f/8.
What worked for me to free it up was put the seized gear in a 250 degree oven for 45 minutes.
I stuffed some crumbled aluminum foil into the hole the shaft of the RA axis fits into so that section
would not expand as fast. It freed up as soon as it came out of the oven!
