Hi All.

I have an issue tonight with dew on my L-enhance filter. This is a 1.25” filter screws into the adapter ring right in front of my ASI533MC Pro camera. I’ve tried clearing the dew with a hair dryer, which took just a second but the dew comes back. I’m not sure how I can deal with this really. Has anyone had this issue before?

I let the dew dissipate on its own.  I never use a blow dryer as it can add dirt to the filter.  I’ve learned over the years that sometimes the best course of action is inaction.  This is one example of that, at least for me.
