| Comment : |
The first object on Messier's list, the Crab Nebula.
It has a diameter of 11 ly but at a distance of 6500 ly it looks very small even in a big telescope.
What we see is a gas cloud after a star that exploded 1054 observed by Chinese astronomers.
Surrounding objects can be seen on this plate solved image: M1 Crab nebula Astrometry.
Later I will use my bigger refractor and take new images, then some details shoud be visible. |
