Adaptive Richardson-Lucy deconvolution demonstration

I've never been a big fan of altering images with photo-shopping techniques, other than an occasional mild sharpening and maybe contrast enhancement with a curve adjustment.

But there is one with a good deal of legitimacy - the Richardson-Lucy deconvolution algorithm -  a software method of enhancing images that was developed to correct the Hubble telescope's originally flawed optics. 

Here is a flashing comparison of an image taken last night before and after applying the algorithm (using ImagesPlus v3.82) -

Here is a still of the finished product:

Note that this is also the product of a nearly 2 year effort to image at close to 1 arc-second/pixel resolution (versus previous 1.4 as/p).
