Where are the flares? With my SharpStar corrector, I had full rainbows across the entire frame.

The vertical stripes on the left and right are from a spider.

Just noticed. Something new for me. Flares are usually radial.

The article mentions rays from bright stars that extend across the entire frame. In your frame, I don't see the owners (stars) from which these rays originate. Or was a lot cropped here? I checked in Stellarium and see that it's cropped minimally. But I also don't see any very large stars nearby. There is the star 20CVn at the bottom left, but it's quite far. On the right, even lower, there is HIP 64540. But this is all strange. On other frames, everything is fine. Did you decide not to use a stamp to remove the streaks?
