In Part-2 of our PixInsight tutorial series, we'll perform permanent, nonlinear stretches, reduce noise, develop amazing detail, and perform many other enhancements using the power of multiscale wavelets transformations.
PixInsight is the brainchild of Juan Conejero, a Spanish software developer who has led Vicent Peris and the 'PTeam' since 2004 in PI's development. If you're new to image processing, PixInsight is a very powerful and much less expensive alternative to Photoshop. New modules are being added all the time, eliminating the need for astro-specific, 3rd-party plugins as with Photoshop. Because it was specifically designed for Astrophotography, it has definite advantages over Photoshop and we can see a time in the near future when its postprocessing abilities will surpass Photoshop in many areas.
