Serge's World

A few weeks back, I processed a few images from the Spitzer Space Telescope, which I posted here

Using the same procedure as I did for my previous images, I downloaded a set of images from the IRAC Map instrument, which takes 4 simultaneous exposures at the 3.6μm, 4.5μm, 5.8μm and 8.0μm wavelength bands.

I then proceeded to artificially colour and merge the images, with each image tinted to blue, turquoise, orange and red, respectively, thus spreading out the bandwidths available across the visible spectrum.
