After all the rain, clouds, bad weather which has troubled many of us for a long time, now we have to protect our lenses on our scopes from the pollen. I do not know about other states, but here in NC the tree pollen is terrible for about 3 weeks, covering up stuff one hour after it has been cleaned.
So for you first time scope owners, I have seen pictures of what pollen will do if it gets on your lenses, especially if it gets damp also, and is not removed properly. I usually do not even attempt to take my scope out during this period, unless it is my small hand held spotter or a quick binocular look. When the pollen gets bad indeed, you may be able to use your scope right after a good rain has washed out the air, but not for long, because it will start right back up.
Here in NC, the pine pollen will get so bad, you can see the yellow dust floating in the air, like a yellow fog, and your sinuses will let you know about it also.
