Spotting Scope Lenses problem

[truck driver]

Has anyone experienced this with their spotting scope?
It's a Bushnell Sportview AF 78-1236 . You can't see this when looking threw the scope.
Wondering what it is?

Looks contaminated in the photo. Probably best to send it in for service. Not an uncommon practice in the camera world.

Fungus on the lenses. Can be the death of optics.

Thanks for the responses. It's still under warranty so it will go in for service and cleaning.

What can cause a fungus to grow in a void that has been purged of air?

What can cause a fungus to grow in a void that has been purged of air?

Moisture inside the scope/lens. Pretty common in warm humid climates. You have a seal somewhere that has leaked. Warranty is a good thing!

I made up a repair order and shipped it off to KS so We will see what Bushnell comes up with.
I also shipped a Trophy rifle scope that a 300 Weatherby broke.

Got a box from UPS today and inside was a brand new Bushnell Sentry Bushnell sent in replace of fixing the old Sports View.
They did the same thing with the Trophy rifle scope and sent a higher value scope to replace it.
The Sports View cost me $30 on Flea bay and the Sentry retails for around $180-$250 depending on where you look.
Since the Sports View was bought for a knock around scope I guess I got a good deal by getting a brand new scope for 19yr old scope.
