This loop is a vast shell of hydrogen shaped by ancient supernovae and stellar winds, part of the immense Orion–Eridanus Superbubble. Spanning hundreds of light-years and lying roughly 500–1,000 light-years from Earth, its H-alpha glow cuts through the Integrated Flux Nebula (the dust). In widefield images usually what is visible is the left part as the signal is stronger.

During many nights I’ve driven to this area to gather enough data to unveil it, making it my biggest integration time published: 28 hours with the H-alpha filter, 4 hours for the RGB. I also captured a big meteor burning up while taking the RGB, which is registered (not randomly placed).

This photo has required so much patience and endurance, as staying all night alone, one day after another inside a car just with yourself really wears you down. All for the love of the game and curiosity to see for yourself what is out there, and how much you can push the camera, your mind and body. One thing that I know for sure is that if I think and I feel that something is worth it, I never give up. I just can’t. I won’t. Through all the rough conditions out there, just keep going because sometimes life surprises you in a good way.
