Hello Bo,

Do you get these markings with both/all your cameras? That would be the first thing to check Vs whichever camera gave you the image you posted. Almost looks like a combination of a water with accumulated dust stain. Which scope gave you the mark - The Meade 10? Then I would look for like carefully for similar shape marks on the mirrors with torch as well as for marks on the imaging sensor of the cameras, etc..

Good hunting

Best
