Could someone help me to explain why I got these ugly blue circle around mars? Collimation? Cool down? Bad seeing? Bad processing? Barlow? or something else.

C9.25 + ultima 2x + ToUCam, 900 images stack using registax.

Thanks,

lei

It's very hard to tell from the processed image. Can you post a raw image?

Clear skies,
