thanks very much again for this nice piece of software. Now, I had a chance to reprocess one video file from last week from solar imaging. I guess, solar was not your intention, but it is "solar system" as well
Anyway, here is active region AR12741 from last week processed with PSS:
It was obtained in continuum (white light, 540nm) using a Solar Szintillation Monitor and GenikaAstro software to trigger image acquisition in moments of calmest atmosphere. Images were stored only if seeing was better than 0.7''. This gave 157 images during a 20sec run. Image scale is 0.21'' per pixel. Further details can be found in the image legend.
The ser-file from GenikaAstro was converted to avi using ser-player software, and then processed using PSS and sharpened with PSS. Image cropping in XnView.
Here is the version processed using AutoStakkert3 from last week
If I compare both versions I like the sharp filament detail in the penumbra and the light bridge in the PSS-version of the image. Also more umbral detail is visible with PSS. I haven't been able to get that amount of penumbral detail with AutoStakkert3 and any other postprocessing software I tried. The granulation cells are sharper in the PSS-processed version but I tend to think that they are a bit oversharpened.
This also hints to the one issue I have with this software: in postprocessing mode I was not able to zoom in into the image to really see the small details during adjustment of the sharpening work. Maybe I missed how to do that from the documentation, but the missing zoom function made it really difficult to judge if image sharpening was appropriate or not. This is not obvious from the image above which is cropped to 760 PX width, but the original file (1920 x 1280px) was much too large to be judged appropriately. With a zoom function I would expect that the final image could be better than the first image shown above. Also, a crop functionality would help.
What was also missing from my point of view was the missing image normalization (flat, bias and/or dark). Flat fielding is an issue in solar since I typically stack very view images (7). There is no related issue visible on the images above but there are dust mottles on the original 1920x1280px file right after stacking and/or postprocessing.
Another minor point is that I used PSS on a 10.6 inch display at 1920 x 1280 resolution. This resulted in text clipping in a number of buttons in the stacking menu and in the postprocessing menu (e.g., "remove" button).
Overall, I was surprised to find that I was able to process this file quickly on a Samsung Galaxy Book Windows 10 computer with m3 processor and 4GB of memory. I know, the video was very small but anyway: I never tried AutoStakkert on that computer before.
Overall, PSS is a very interesting software but as with every new software I need to get used to the individual steps and the somewhat changed workflow. From my point of view what is really missing is image normalization (flat, bias, dark) in stacking mode and the missing zoom function in postprocessing mode.
Rolf, please see my comments as enthusiastic replies and meant to help you further improve PSS if you think it is feasible. Anyway, you really achieved a lot in very short time - thanks again to support the astro community with your open-source!
