M42 Orion Nebula

One of the most visible, beautiful and easily identifiable of the messier objects in the northern hemisphere. Situated below the belt of Orion about 1200 light years away , the Large Orion nebula is a large cloud of star forming clouds and dust . The centre 4 stars are part of the trapezium cluster where stars are currently forming.

Here are two narrowband images of M42, with channels swapped around to give different colours. As this is a false palette there is no right or wrong method of mixing, but I prefer the second image. I did not use larger subframes as , even at 30 seconds, I was overexposing the trapezium.
