Condensation inside polar scope

[Swoop1]

I went to polar align my HEQ5Pro tonight but found that the inside of the polar scope was condensated and insufficiently clear so failed. 
The misting seems to be on one side of the reticle element. 
I really don’t want to remove the scope as previous experience of collimating a scope to a mount was very painful.

Can anyone suggest a solution?

Thanks.

Portable hairdryer down the hole?

That was my first thought- I have a spare socket on the power box so will borrow Mrs. Swoop's spare dryer next time I go out.

Quick update- hairdryer did the job sufficiently enought that alignment was acheived (for now...)
