This is a SOOC unedited jpeg only resized for the forum. I found this piece of debris on my sensor over a week ago and used a rocket blower to try to remove it. Obviously the rocket blower didn't work. I will try it again, but if it doesn't come off, I am hesitant to do a wet cleaning--only because it's rather large and I don't want to risk scratching the sensor with something so big. Any suggestions?
