| Exp. time : | Blue plate 8 minutes |
| Image process tool : | AstroImageJ, Fitswork, Irfanview |
| Processing : | High pass filter, radius 50 pixel |
| Comment : |
With a high pass filter it's easier to see the structure in the filaments of the nebula,
this is only the POSS-I blue plate, the red plate looks almost the same.
The black center part because it's overexposed.
There is a lot of star births in this nebula which can be seen in the Hubble data. |
