This is one of several shots i took its obvious the moon is out of focus thats ok iam not really worried about that happened by accident but iam wondering what the object behind the moon is has any one got a clue this was a experiment i was conducting using a circular polarizer this is striaght out of the camera sensor dust and all thanks

Looks like lens flare to me. Reflections inside your lens/camera can sometimes make it to the sensor. Usually happens/is visible in dark scenes with small, bright sources.

Shhhhhh.
You're sposed to say "it looks like a stray planetoid, have you repported this to NASA" ; )

Right! "You've captured an image of the secret moon-orbiting military space station. Your home address has been recorded and you will be visited by some re-education shock troops. Have a nice day!"

LOL LOL ahh i see because the shape that was led to beleive different but i wasnt sure and i know lens flare. i dont think this happended without the polarizer so iam going to assume that was a major factor
thanks

It's a reflection off the inside coating of the lens tube of your camera.
You'll find that if you take a similar shot again, but place the moon further to one side of the image, and expose similarly, that other object will move symmetrically with your moon. If the moon was in focus, that reflection would be too. I had this happen with my 602 when taking shots of a partial eclipse of the sun one time, and I believe the S20 is a very similar construction.

For this shot i was using the S1 Pro and i was using a tamron 70-210 f.4 but iam pretty sure the same applies though

Is your polarizer multi-coated? This might be a good example of why you should buy multi-coated filters.
If it is multi-coated, then i guess it's just proof that the multi-coating is a waste of money :)

For what i paid for it i doubt that its multi coated but in any event the fact that it is multi coated prevents issues like this from happening? thanks
