Re: RC BlurXterminator …. Any comments ?

@Mike in Rancho have you read Shaun's Experienced Imaging thread about his "convolve then deconvolve" experiment? There was discussion from Rista about noise profiles (I guess so, because you thought Shaun's new thread was about the M101 data). Anyway, I expect you're right that applying SVD to the...

Re: Astro to Astro-art Continuum, 2024 Edition

This is brilliant Dietmar - I love seeing people dive deep into what's happening (and taking others along for the ride). :bow-yellow:

Re: Astro to Astro-art Continuum, 2024 Edition

Hi Ivo, thank you for these additional comments, and for 'translating' them into their audio equivalents. I wonder if the audio analogy has it's limit when we look at the default settings of the scale sliders. By default, details of all scales are sharpened (100%). In terms of audio we would push u...

Re: Astro to Astro-art Continuum, 2024 Edition

Wavelet Sharpening in StarTools is indeed "more" data driven than a regular wavelet sharpener, in that it uses more statistics and analysis of the data to achieve two - for AP generally - desirable things; it refrains from boosting areas that don't have enough signal (uses Tracking's signal evolutio...

Re: Astro to Astro-art Continuum, 2024 Edition

If it helps, almost every processing algorithm/technique has an equivalent in "1D" such as in audio/music; For example; Wavelet sharpening is about isolating and manipulating specific frequencies (like a graphic equalizer). Deconvolution can be thought of as undoing the effects of a reverb/reflectio...

Re: StarTools 1.9 Beta

Small update again (1.9.561 beta 5). Chasing some odd bug that passes file dialog clicks onto StarTools on some OSs. For any macOS folks running Ventura and later (e.g. hixx ?), I also added a new way of unquarantining that I'd like to roll out if it works reliably; control + click on StarTools.app....

Re: Sky Glow parameter in FilmDev

Hi Jeff, Thank you for your post. What you appear to be suggesting would constitute data clipping/destroying (e.g. throwing away pixels below a certain threshold). This is almost never OK, except in cases where that data can be assumed to be anomalous. For this purpose you will already find a "Dark ...

Re: StarTools 1.9 Beta

Small update with some bug fixes, UI fixes and getting rid of (hopefully) the last "UNKNOWN" log entries. :)

Re: StarTools 1.9 Beta

Hmmm... Yeah. That's not exactly intuitive. Will fix! Thanks, Ivo. :thumbsup: Not a priority of course, especially now that I (and hopefully others?) have a bit better understanding of what Bin is wanting to do for us here. Just something for the list of UI tweaks on the path to the final 1.9. Now ...

Re: StarTools 1.9 Beta

Hi Mike, I think this is expected behavior, and should only happen if you have chosen an integer binning mode. In that case, there are only specific "sweet spot" percentages that allow for an integer factor bin. Is that what's happening? Hi Ivo. I'll give a qualified -- aha! This starts to explain ...
