Description

The same set of stacked raws as in the "Trifid and Lagoon nebula" image but with a different processing. In this reprocessed version I followed some of Roger N. Clark advices regarding color stretching of stacked images and the rnc-color-stretch code provided (http://www.clarkvision.com/articles/astrophotography-rnc-color-stretch/). The results are indeed far more natural colors with a better dynamic range and a more "powerful" histogram.

These two simple work case scenarios highlight the value of the processing techniques applied in the hierarchy of the final image quality. The present reprocessed image, also, gives some clue on the results someone would expect without the use of any guidance, filters or specialized equipment besides an old entry level DSLR (canon EOS350D), an inexpensive zoom lens (Tamron 70-300mm f4-5.6) piggy back on a good mount (EQ6 classic) with good orientation.
