Yes, of course I tried, and it doesn't solve that artifact.decay wrote: ↑Mon May 22, 2023 5:28 pmHi Carles,
this looks a bit like the artefacts we discussed a few days or weeks ago:

(There have been some more posts regarding this issue in the "StarTools 1.9 preview" and other threads.)
Have you switched on the 'PSF Resampling' 'Centroid Tracking' option and/or checked for dud PSF samples?
Best regards, Dietmar.
Yes, I was selecting PSF's, and tried different ones, different sizes (unselecting previous then selecting new ones )Mike in Rancho wrote: ↑Sat May 27, 2023 9:31 am Yeah Carles, the new SVD and deringing regime can be a bit finicky, dare I say tempermental?
Your shadowing is really shifted though, which kind of points towards a bad sample. Were you loading PSF's at all?
I actually ran across that little snafu tonight after a restack that was very very similar, but had actually used a slightly different reference frame. When I loaded the PSF samples txt from previous processing, the selected sample boxes aren't recentered on their stars, and so I had a slight wobble to my ringing and shadowing that looked similar to your image.
I'm still struggling myself. Sometimes you can go back and alter early workflow, such as DAF, IFD, and the OptiDev, but for one, that really starts driving processing into one narrow path just to get SVD to work, and two that doesn't always solve things anyway.
It still strikes me that 536 deringing might be nice as an option B, though maybe that algorithm is obsolete due to the other changes in SVD. I probably need to practice and experiment more, but right now I'm spending a lot of time making custom masks for shrink-dering, and since that doesn't always fully repair the flaws or has sufficient color match, custom masks for layer blurring as well.
Here's one I had earlier, one little crop region that displayed a very heavy dark ring (SVD just may not like my Newt), nearby stars that seem basically unaffected, and then a couple (one in particular, lower and 3/4 right) with almost a reversal or ghosting from the deringing.

On another, and probably easier, note, in Color the Before-After toggle button only shows Before-Before when in MaxRGB screen. It still toggles correctly, just the button doesn't change.
Same here with W10 , Ryzen 7 5800h , RTX3070, 64Gb ram. latest sdv decon takes quite a bit, gets sort of "frozen" to the point of not being able to select a preview rectangle either for few seconds, and also each sample selecting makes this happening.1.9.551 Ubuntu 22.04 i5 8Gb
Hi everyone
SVDecon sampling takes -quite a bit- longer than previous versions and you can''t 'mouse ahead'; you have to wait for the star to be selected before moving on.
Anyone?
Cheers and clear skies,
Steve
