The brightest star in the lower-left corner of the high-resolution image appears to have a red X centered on it (a very flattened X at a slight clockwise angle). Is this visible in other images or simply an artifact in this one? I don't see it around any of the other stars in the image, so I don't think it's a diffraction artifact (oh, you're using a refractor, so that couldn't be it anyway). If it is in other images, what are we seeing?

Yes, I have too much time on my hands.

Thanks,
Derrick Baumer
