A Reprocessed Spitzer View of the Galactic Core

This is a view using FITS file mosaics generously provided courtesy of Susan Stolovy, with attribution to Rick Arendt and Solange Ramirez for their work in producing the final mosaics. Her team used a processing technique that alleviated some of the saturation issues arising in some of the brighter parts of the mosaic that one might find in the mosaics provided by the Spitzer archive.

 

My take is not necessarily much different than what's already been done, but it is quite a bit less saturated than what you can find on the Spitzer website, and just a bit more of those wispy dust and gas formations can be made out. Anyway, it's nice to work with some data where someone else has already done most of the work.

 

For reference, here is a link to the original version using the same wavelengths on the Spitzer website: www.spitzer.caltech.edu/images/1540-ssc2006-02a-A-Cauldro...

 

Screen: 8.0 µm (IRAC4)

Red: 5.8 µm (IRAC3)

Green: 4.5 µm (IRAC2)

Blue: 3.6 µm (IRAC1)

 

The image is presented in galactic coordinates, with north up in that regard.
