TThe
Rosette nebula is about 4700 light years away in the Perseus Arm of
our Galaxy in the constellation Monoceros. Its about 130 light years
in diameter.
The
young open star cluster at the centre is NGC 2244 is only a few
million years old and is only visible using binoculars or a small
telescope. However the red Nebula can only be shown in detail using
modified cameras with light pollution filters. The hot bright stars
in the centre are super heating the gas cloud of hydrogen gas,
ionising it and making it emit red light in a specific wavelength.
