Dear All

Is it possible to reduce the red star borders?

Best Regards

Hello Stefan, the halos caused by the glass optics seems normal to me. Compare it to this image:

Instead, the overall background seems too bright and too reddish, this should be corrected and made similar to that image.

Best regards,
Fabio.
