This week we feature what I call the “Thunderclouds Region” of Orion. Lying between M42 and the Running Man nebula we see this chaotic H-alpha region which to me looks like a brewing thunderstorm.
This is a VERY OLD image taken using the original Hyperstar on a C11 SCT with a tiny little H9C OSC CCD. It is a single frame of around 120 x 1-minute subs.
