It was a great astro marathon last week! So many objects, dark clear nights. Just a gift! .... Well, now the sky is closed (I hope, not for long). Finally, I'll get some sleep=)) .

Wow) I have a feeling you're shooting without dithering.

There is noise resembling a "coroied" plaster texture. This is called walking noise.

I'm very familiar with dithering. I just don't understand where this noise is coming from if dithering is applied by default. Could you please justify your criticism?

Iren, it's good that you know about dithering. It's not enabled by default because it still needs to be configured, especially when using ASIAIR. Now, regarding the characteristic noise. Don't you notice it yourself? I can only point it out, since I can't attach a screenshot with arrows.

Well, there's also a slight bit of defocus here, if we're being really picky. You somehow missed that one.

I wasn't nitpicking. I was just sharing my observation. The work is great, but for some reason, there's a characteristic noise that reminds me of the noise that appears when there's no frame offset. That was my first guess. But do you understand what I'm talking about at all? What are your observations and thoughts on this?
