The Orion Nebula (M42)

The Orion Nebula, designated as M42 or NGC 1976, is one of the brightest and most famous nebulae in the night sky. It is located in the "sword" of the constellation Orion, directly below his distinct belt, and is approximately 1,350 light-years from Earth.

It is an emission nebula – a massive cloud of gas and dust where new stars are being formed. Inside lies a young star group known as the Trapezium cluster, whose intense radiation ionizes the surrounding gas, causing the nebula to glow in distinct shades of red and violet (and green in narrowband astrophotography).

Thanks to its brightness, M42 is visible to the naked eye as a misty patch. Through a telescope or in a photograph, it reveals an incredible amount of structure, folds, and detail. It is one of the most popular objects for both observation and imaging during the winter months.

Acquisition

This was my second winter project; I followed up immediately after finishing the HorseHead nebula and moved straight to the Orion Nebula. Personally, I don't think I managed to capture the colors exactly right, largely because I processed it just a few days after the HorseHead. Furthermore, the integration is a bit shorter (only 4 nights), and I had to discard quite a few frames. Even so, it is a very beautiful nebula, and I plan to return to it again.

Acquisition took place on these nights: Dec 28, 29, 30, 31.

Once again, everything was captured using N.I.N.A and PHD2

Processing

The classics: DSS, PixInsight, and GraXpert. The Starless image was created via Starnet again.
