The Power of Post Processing

I've been toying with a variety of photo editing programs and in the following image, I really boosted the "clarity" (contrast) of an M31 image I recently posted, as seen here.

Admittedly a bit "grungy", or noisy if you prefer, but notice how much more detail is brought out around the galaxy's core, as well as the dust lanes.


The devil is in the details - and so are the data. :O)

(Adjusted in Topaz Studios /http://www.topazlabs.com/ )

A larger size of the above comparison can be seen here.

And here is a larger version of the new image.
