Hi

The camera sensor was cleaned with above cleaning solution.

This is the latest flat frame with the camera attached to my refractor telescope: https://www.dropbox.com/home?preview=flat.jpg

Unfortunately the streak cannot be gone it is indeed a little scratch on the ccd sensor protective layer.

But the good news now.

This is a 20 min test light frame exposure: https://www.dropbox.com/home?preview=light-20min.jpg

This is the light frame calibrated only with the flat frame: https://www.dropbox.com/home?preview=light-20min---cal.jpg

Success the streak is gone also the dust motes and vignetting. Flat frame made its magic :)

Let's consider this topic as closed.

Thank you all for your support and understanding

Regards, Konstantinos
