Wide angle astrophoto of the famous nebula Orion or M42.
From the balcony I have a narrow free view I can use, 20 minutes and it's gone.
Wide angle photos are amazing, look at all the details. |

To take a photo from our balcony of Orion Nebula isn't easy, just a few hours per year we have it in correct position between the houses.
And when it's there it's just above the roof of a house. The heat from the house cause a lot of turbulence in the air.
Still there is a photo of it and this nebula is one of the most beautiful, and it's bright too.
It's about 25 degrees above the horizon at this time. |

This is a 1:1 pixel crop of the above photo, because of the turbulence from the heat above the roof it was impossible to get the focus correct.
But who cares, the nebula is there !
In the center where it's over exposed is the Trapetzium, four very bright stars.
If I get the opportunity I take new photos with less exposure to get that part of the nebula correct exposed. |

Out of focus to bring out the colors of the stars.
The red star up to the left is Betelgeuse.
It is a super giant M-star, 800 times the suns diameter,
but it's mass is only 20 times the Sun's |

M42 is the red veil in Orion's sword under the belt (the three stars at the top).
This is the first photo ever for me on this nebula. |
