I'd say it proves nothing Leon. You could take the same phot with your scope mounted on a tripod. If you G11 is a 'goto' there is in my opinion only one valid test for polar alignment, and that is 'goto' accuracy. Guiding will cover up small errors in polar alignment, but a 1 star alignment followed by some goto operations will tell you how well polar aligned you are. A good polar align will repeatedly place a target on a webcam chip, or be close to central on a DSLR sensor. Drift aligning is good, infact mandatory, but after drift aligning, a sure test is goto accuracy. All your image shows is that the scope was ponting south. Where was your polar axis pointing? How parallel to the Polar axis is your OTA?

cheers,
Doug
