Spiderweb in the ED80

While processing some frames of The Pleiades I noticed a strange diffraction pattern on the brighter stars. Further investigation was called for so I brought my ED80 in from the observatory and looked it over with a bright flashlight. See what I found...

Here you can barely see the web stretched across the lower left on the inside of the OTA.
