Description

This HII region, including the Orion nebula located 1300 light years from Earth, has a very high dynamic range. In this image, obtained in narrowband H-alpha light,  I combined 8 pairs of 1 and 5 minute exposures to capture it. The combined image is then processed to compress the dynamic range again, but with preserved details.  This changes the appearance of the nebula quite a bit from how it would look like visually, but makes it possible to see much more details.  I made both a black and white and a colored version and include both. Personally I like the colored version best, but I think they show about the same details.
