Description

After wasting several nights of imaging due to a real strange mottling effect in my images which I could only see once I integrated them, I found the problem. I decided to take off my dew shield and clean the camera window. Well I didn't have to go that far.

Apparently an arachnid decided to make his home on the corrector plate of the RASA. It was entirely covered with webs. Man those little suckers work fast. Well he met his demise! LOL!!

This is the result of the eviction and termination of the 8 legged monster and his web!
