Thanks to Mike (Borodog), I've had the opportunity to begin working with the blind deconvolution program BiggSky.  I'm only 2 days into my exploration of the capabilities of this software and so far I've been nothing but floored.  Even my errors have still contained something to learn.  I just finished another run of my data from May 19 and decided to crop around Copernicus to the same margins as the image I produced last week using the ROI tool in Wavesharp.  I'm still working on color palette differences between the two (but I'm getting better all the time).  The sharpness of the BiggSky blind deconvolution is quite impressive.  Runs on full-chip ASI678MC stacks take well under a minute to run and the entire image is just as sharp as this crop comparison.  Just wanted to let y'all see the results for yourself.  Note:  I've spent the better part of 18 months working with Wavesharp, and it's an excellent program that delivers great results.  But, at least for lunar, the blind deconvolution algorithm seems to equal and in reality exceed the results I've been getting with Wavesharp.  What I need to try next (and I didn't think of it until now) is using the PSF Denoise tool in Wavesharp after deconvolution in BiggSky instead of the denoise tools in Image Analyzer.

Is this the best of both worlds?  BiggSky Blind deconvolution followed by Wavesharp PSF Denoise and the excellent Histogram and RGB Align tools.

Could you post a link to BiggSky? A search returned a lot of false positives.

The picture in #1 is a comparison between 2 different post-processes, as far I can gather?

 

All I can say it looks great in stereoscopic view, when maximized. The best of two worlds obviously do not interfere that much, and deliver a very sharp 3D-view, truly the synthesis of both worlds.

Sorry but I don’t have one yet.

Picture #1 is a comparison between wavelet sharpening with Wavesharp compared to Blind Deconvolution with BiggSky. The post processing is not relevant (darn phone keyboard) and very similar in any case.

It is an interesting piece of software that seems to maximize the efficiency of deconvolution in an image. I hope Dr Biggs will make it available to the public at some point. I thought after his presentation on the Astro imaging channel it would have been released as a PixInsight add-on or other software either as freeware or paid.

Have you compared BlurXTerminator results to these others? I've been using it with lunar photography at lower magnifications with great success.

If you would like to get access to the BiggSky beta, please send me a PM.

Not tried BlurXTerminator.  BiggSky is a sharpening technique using deconvolution.  Denoise is a post process effort and franky BiggSky yields such a small noise signature you almost don't need to remove it, especially for wider expanses such as, for example Plato down to Hadley.

 

Here is my most recent run using my data from May 19.

 

Post processing was done in Image Analyzer.

I also discovered a way to crop specific parts of the image out during the deconvolution step.  Here is a second run of the previous stack but cropping Tycho out during deconvolution.  Again, post processing was done with Image Analyzer.

 

 

Mike had trouble doing planets with earlier versions of BiggSky and if I recall needed to blend in some of the unsharpened image to tame the harshness.  I'm looking forward to trying this out on planets in any case just to see what it can do.

 

The details on Tycho came out nice without harshness to my eye.

Here is anther comparison between BiggSky (on the left) and Wavesharp (on the right).  Tycho was cropped from the full frame within the respective software packages.  Both final images started from the exact same unsharpened stack.

The BiggSky (left) image looks to have green and purple coloring. Any idea what that is? Maybe you did a color align in wavesharp and not in BiggSky?

Haven't been worrying the colors yet for the BiggSky processing since it's just sharpening routine.  The Wavesharp image was fully color balanced.
