Messier 42 - The Great Nebula in Orion (positive)
Near IR / SII / H-alpha image of the large star forming gas cloud in Orion.
Distance estimates are 1344 ± 20 light years so that the cloud is about 24 light years across. About 4 hours of light. Images were stepped in 2-stop increments from 0.25 sec (for the core) to a couple of minutes.
All the images were calibrated then stacked using sigma-combine. They were then log-stretched and then layered in PS. burned out regions were masked and feathered to the next shorter image group.
This is the same data set as the negative but the contrast was jiggled to enhance the core at the expense of the outer areas. The principle stars in the Trapezium (Theta Orionis) that light up the nebula are readily visible. Also visible are many faint stars that do not appear on visible light images of the nebula.
