| Comment : |
The Bubble nebula is famous for its shape and beauty.
This a crop of the full frame sensor, to fill the sensor up with the nebula at least 6 meter focal length telescope is needed.
Surprised how good I got it at this out of season time and it was only 30 degrees above the horizon too. |

If you look at the full resolution image you find more objects.
This is the nebula NGC 7538.
About the same distance but half size. |
| Comment : |
The third object is an open cluster, M52.
This cluster is only half the distance from us, 1400 ly.
It has a mass of 1200 Solar mass.
Our Sun was maybe included in a cluster like this in its younger age. |
