This is an extreme detail of one of the most studied star forming regions that we can find in the sky: the Orion Nebula. Specifically, this image shows the so-called Trapezium area. This area is the brightest region in this difficult object. It was taken with a 60 inch telescope atop Mount Palomar, CA, USA. I want to thank Paul Gardner and the Palomar Observatory for supplying the raw frames for processing. The images taken with the Halpha filter were used as Luminance and not blended with Red, in order to get a better color balance.
A wider field mosaic, taken with a 20 inch telescope can be found here.
