Official StarTools support forum

Hi all, With the exceptional help of decay and hixx , multi-language support is coming along quite nicely, making StarTools more accessible for non-English users. :thumbsup: We now have a rudimentary French translation, but we could really use the eyes and brains of some true native French speakers ...

I'm definitely not proposing we should be doing 16-bit stacking, however the assumption is that the source material is *multiple subs* of 10, 12, 14 or 16-bit quantized data, where values fell within the range of 0 to /1024, 4096, 16384 or 65536. Stacking multiple subs will - in essence - add 2^(sta...

The plateauing can be caused by a number of things and would - as already mentioned - be chiefly caused by an area that shows comparatively very little change in co-located pixels (as a proxy for "detail"). It would therefore receive a smaller dynamic range allocation. I've seen this happen as a res...

@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...

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

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...

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...

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...

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....
