| Notes | Abell 39 is a
dim, spherical Planetary Nebula in Hercules. I used
data from the Ha signal to boost the Red channel and added a bit of Ha
to the Blue Channel to represent the H beta channel. OIII data was
added to both the Blue and Green channel. The narrowband data was
used only to emphasize the planetary nebula and not in the background
stars. |
