Interesting that the halo is square around Alnitak. How’d you do that?

It’s an artifact from the camera. The ASI1600 has microlenses over each pixel on the sensor, which makes this pattern around bright stars

Thanks for the reply. I’ve never heard of such a thing, but I’m a beginner and glad to learn.
