Scope image looks white

[MartyK2500]

I just purchased my 4th scope last week.
Since it's for a 308 that will see something like 200-250 rounds a year, I decided to go cheap and put a Vortex PST gen 1 6-24 SFP.
Now I am wondering if it's because it's too cheap, or if it's defective.

Everything in the scope looks bright white, almost as if everything has a drastic colour contrast through the scope.
It doesn't do this in my 3 other scopes (4-27 Razor gen ll, 1-6 Razor gen ll, Acog)

I am not talking about the black tunneling related with improper eye relief placement either, as this is normal and scope is set up properly.

Anyone know or has seen what I am talking about?

Moisture most likely... send it back in for warranty

Seems odd. My cheaper Viper does not do that. Looks like another Vortex failure.

Yesterday afternoon i left it in the sun, i presumed if it had humidity it would have droplets inside the glass.
I also noticed, that the whiteout is caused by sunshine, even with the sunshade on as soon as it’s too bright out, the PST gen 1 will lose it’s colours compared to my 3 others.

Shot good groups with it yesterday, it still works but i wouldn’t use it for a main rifle let’s say.

I guess you need to compare it to another exact one.
