Photo description / processing

It turned out masterfully, as the object was captured under extreme conditions. During the shoot, a solar wind surge hit and the sky was simply ablaze with aurora. I didn’t stop shooting, although on some frames the aurora still broke through despite the filter. Processing by @CAHEK_61.

Cool, it looks like an X-ray of lungs.

Thank you. Well, yes, there's something to that. But it reminds me more of a butterfly.

And where do the rays on the refractor come from?

A mask with a cross-shaped aperture for collimation. After using a Newtonian telescope, I really liked the way stars looked with it, so I made this mask.

The beauty of a reflector is that you can easily stack data from multiple imaging sessions, even over several years.
The diffraction spikes here would get in the way.

Thank you very much. I'll keep that in mind. I hadn't thought about that before.
