Astronomy Science data |
Content: |
|
The first data archive I used was the POSS data, behind that letters stand The Palomar Sky Survey. These are really old data, not taken with digital cameras, it's from the old photo emulsion era. But they are still very interesting. From here you can get wide field images that you can compare with your own images. It let you know, are todays amateur astronomy cameras better or worse then 70 years old technology? |
Messier objectsTo learn how to use these data archives, I first do test with Messier objects. I think most people with astronomy interest know about Messier, if not you can get more information from the link below. Below you will see which objects I have selected, the idea is that you can compare these photos from different data archives with your own: |

Messier 13 Hercules Globular Cluster |
Messier 31 Andromeda Galaxy |
Messier 42 Orion Nebula |

Observatory list and data archives:The idea is that you shall find above objects at each observatory/data archive I list below:
I hope you will find it very interesting to know more about these archives and the telescope that it was taken with. |
