Hello everyone.

I would like to present to you a (relatively) new astronomical opensource software: Siril (http://free-astro.vinvin.tf/index.php/Siril). It's an image processing tool, able to convert, pre-process, register and stack images. Siril is build ON and FOR GNU/Linux but it also works on MacOs (http://free-astro.vinvin.tf/index.php/Siril:install#Installing_on_MacOS).

Siril is dedicated to deep sky AND planetary images. Indeed a large amount of format are compatible:

FITS    (*.fit, *.fits, *.fts)BMP     (*.bmp)NetPBM  (*.ppm, *.pgm, *.pnm)PIC     (*.pic)RAW     (*.dng, *.mos, *.cr2, *.crw, *.bay, *.erf, *.raf, *.3fr, *.kdc, *.dcr, *.mef, *.mrw, *.nef, *.nrw, *.orf, *.raw, *.rw2, *.pef, *.ptx, *.x3f, *.srw, *.arw)TIFF    (*.tif, *.tiff)JPEG    (*.jpg, *.jpeg)PNG     (*.png)SER     (*.ser)AVI     (*.avi, *.mpeg, *.mpg, *.mp4, *.webm, *.mov [from DSLR])
  • Preprocessing:

Siril's works internally with FITS images, unsigned 16-bit per pixel and per channel. All images you want to process with Siril thus needs to be converted using the Conversion tab, except for SER and film sequences which are converted on-the-fly.

Image registration; supported methods:

  1. Translation using DFT centered on an object, generally used for planetary images
  2. Translation using PSF of a star, generally used for deek-sky images
  3. Manual translation with two preview renderings of the current image with reference frame in transparency
  4. AND the very new global star alignment automatic tool !!!! (http://free-astro.vinvin.tf/videos/Star_registration.webm)

Image stacking methods (several algorithms come from PixInsight Documentation):

  1. Summing
  2. Median
  3. Percentile clipping
  4. Sigma clipping
  5. Median sigma clipping
  6. Winsorized sigma clipping
  7. Linear fit clipping
  8. Pixel maximum
  • Processing

Siril also processes your images after the first step of pre-processing. To do that we implemented some algorithms very useful and dedicated to astronomy images.

  1. Histogram Transformation (same algorithm that the one used in PixInsight)
  2. Color calibration (http://free-astro.vinvin.tf/videos/Color_Calibration.webm)
  3. Remove Green Noise (same in PI or HLVG in Photoshop) (http://free-astro.vinvin.tf/videos/RemoveGreen.webm)
  4. Color Saturation
  5. Median Filter
  6. Fourier Transform (http://free-astro.vinvin.tf/videos/FFT.webm)
  7. Wavelets
  8. Canon Banding reduction (same in PI) (http://free-astro.vinvin.tf/videos/fixbanding.webm)
  9. Background Extraction
  10. RGB compositing (http://free-astro.vinvin.tf/videos/RGB_compositing.webm and http://free-astro.vinvin.tf/videos/RGB_compositing2.webm)
  • Analysis
  1. Dynamic PSF Tool (http://free-astro.vinvin.tf/videos/DPSF.webm)
  2. Gaussian Noise estimator

And some other tools in command line.

Here some results obained with Siril :

I hope some of you will enjoy using Siril.

I wish you all the best !

It's nice to see a new addition for those of us who would like to do everything on Linux but who are still tied to windows for different reasons and constraints ;)

I will try Siril asap. How can we contribute ? Translation, bug reports, beta tester ?

Cheers

Hello. Thank you very much.

Of course you can contribute :). As you may see, english is not our mothertongue. So sometimes senteces used could be ...


bug reports, beta tester : of course, it always helps :).

For now this version is not totally stable. We are some items left in the TODO list.

Thank you so much

I work at SuSE so I'd be glad to contribute any way I can. I am not a dev though but I am technical and have access to a lab for testing (on my spare time of course... Hi boss !)

Feel free to PM me if you need help with documentation, testing or translation. I'd be happy to get involved.

Good luck on your project :)

Nice :D

I've been OTT busy with job applications and interviews but hopefully when this calms down (with a job) that I should be able to start contributing to the astronomy world again!

Hello.

It may have a bug in the current version. If you cannot run the current version, take the revision 891

svn update -r891

James if you know how to make it, I think It could be wonderful :)

Well, I have an executable built on Snow Leopard that should hopefully execute on all later 64-bit releases which is a start, but there are some niggles with it at the moment, a couple of which will have to be fixed before the application is actually useful to anyone using much other than SER files.  I'll see how I get on with those over the next few days.

I'm still working on this, in particular trying to get ffms2 to compile which I believe is required to be able to read AVI files.

It appears that this may well be pig-awkward to do for OSX 10.6 even if I build on 10.7 because some stuff just isn't supported by Apple on 10.6.

Does anyone have any particularly strong feelings about having this work on Snow Leopard?

Looks like I may be making progress on this.

This morning it occurred to me to try to compile previous releases of ffms2 on Snow Leopard instead of trying to use the latest and found one that does work.  I don't think it should be a big deal that it isn't the latest version as the changes since then don't appear to be major issues that might affect astro type images.

I've also done the same thing with openCV.  The latest 3.0 version won't build on Snow Leopard, but 2.4.11 will, so I've installed that.

I'm hopeful that means I now have siril building with all the functionality it needs to be useful.  It still doesn't run correctly, but I think it's just some minor code tweaks that are required to sort that.

I'll post more news when I have it.

Hello James.

Unfortunately that is not true. The last version of ffms2 took into account some fixes we asked. Indeed, during our tests we have seen that some videos from astronomy cameras were not read (avi format).
