These add-ons for Celestia v1.3.0 (or later) display a montage of
six images of the Eagle Nebula
and its associated galactic cluster, M16. They also include an STC file
defining 74 of the stars in the cluster. (Some of these star
definitions specify star names, which requires Celestia v1.3.1pre3 or
m16-v2 contains transparent images,
the images included in
m16-v3 are opaque.

The easiest way to install these add-ons is just to expand the .ZIP archive into Celestia's extras directory. Zip will automatically create the subdirectory m16-v2 or m16-v3 and its contents.
These archives were updated on 6 July '03 with improved coordinates for the M16 cluster members. Their revised locations also are available in this separately downloadable file:
The Eagle Nebula and M16: full view
The Eagle Nebula and M16: closeup
Eagle Nebula with opaque cold gasses
The Pillars behind the gas
A closeup, behind the covers
||(2Kx2K)||A false-color image of the Eagle Nebula, from NOAO|
||(1Kx1K)||An infra-red mosaic of stars in the Nebula, from 2MASS|
||(2Kx2K)||The famous picture of the "Pillars of Creation," from NASA|
||(2Kx2K)||A high resolution infra-red mosaic of stars, from ESO|
||(1Kx1K)||A closeup IR image of the top of Pillar #1, from ESO|
||(1Kx1K)||A picture showing the cold nebulosities (-100 degrees Centigrade) that fill the Nebular region, from ESA's ISO.|
m16-v2, all but the backdrop,
04086.dds, incorporate alpha channels
which let you see though them to the images behind.
m16-v3, the alpha channels of all of the
images eliminate only the black borders.
Borders were added around the smaller images instead of scaling them up to a size needed by Celestia. This should limit the damage done to the resolution to that inflicted by your graphics hardware. However, two of the images, "04086" and "phot", were scaled down from much larger versions available on the Web.
Hopefully soon Celestia will allow selecting among Nebula textures as it does among alternate planetary surface textures. In the meantime, you can edit m16-v2.dsc and comment out the Mesh declarations of those "billboards" you'd like to ignore.
This add-on has several limitations which may be corrected in a future version.
The original images were created by the research groups credited below.
