I'm going to try and use the Goto feature so that I can find Pluto. I've yet to use the Goto feature properly.
I got home late last night and I thought of getting the scope out then but I thought the Moon was too bright and would spoil the view.
I'll see what happens tonight and tomorrow night. It's suppose to be clear. Next weekend is supposed to be raining.

I think you will need to wait until the moon is out of the way before you go for Pluto. It is fine to look at the other planets even with a full moon, but Pluto is a bit too faint for that. Currently around 14th magnitude means it is a real test for a 9.25" scope and a novice astronomer even when the moon is out of the way, especially with some light pollution.
Regarding the cooling: if you put your scope out at sunset it should have cooled nicely by the time it is dark. Don't face the glass straight up though, keep it horizontal while it is cooling- otherwise you might get dew (or dust) on the objective. (It is a good idea to get a dew shield if you don't have one already.) BTW, this applies any time you leave a scope with glass at the front (SCT, refractor etc) out and unattended- try to make sure the glass can't see the sky- otherwise if there is any dew around it will get you! (That may mean covering it with a cloth even if there is a dew shield.)
Good luck!
