 There is probably no more difficult object in the sky to properly photograph than the Orion Nebula. It is so bright in the core, making it impossible to capture the outer gossamer beauty and inner core trapezium star cluster in a single frame. This image is a composite merged from half a dozen images ranging in exposure from 2 seconds to 20 minutes. Keeping the colors uniform over such a huge dynamic range is challenging, which is why I had never attempted this object seriously. Here is a stab at this object, and while not perfect shows the most I can capture with my 12 inch and DSLR.

About M42

About a degree in size, this 4th magnitude nebula is the brightest of its type in the entire sky. It is a huge hydrogen cloud that has been ionised by the high UV from the tiny central star cluster.
