I do enjoy my Andrews 80 degree 30mm ultra wide for finding stuff.
Over the last few months, it got left outside and then packed away in its case. I then took it out next viewing and noticed the moisture inside the glass.
HMMMMMM, how do I fix this??
Last night after many attempts at leaving it in the sun to no avail. I put it in the fan forced oven at around 50 degrees for around 2.5 hours
Eventually the moisture inside the unit had disappeared and everything is hopefully back to normal.
Now, if it was a 31mm nagler???............I do not think I would do this, but then again, 31mm naglers would not allow moisture to get inside.
