I've been following SCA260 on a CN forum and noticed that many people are using it. So I bought one this year. Since receiving the product, I've been testing it for half a month, but the star points have never been as good as those I saw on the forum. I'm not sure what went wrong. Could you all help me take a look? Attached are the test pictures bin2x2.

Because of the double diffraction spikes and donut-shaped stars, these two shots appear to be out of focus
