February 13rd, release udpate # Due to a crash with some FITS files of the 0.99.8 version (generally coming from ASIAIR system), a bug fix was quickly released under the 0.99.8.1 version. We encourage everyone to update their software, even if Siril says that everything is up to date.
The release # This is the third beta version of the upcoming 1.0 version. It comes with many improvements and bug fixes over the second beta (0.
One month after the release of the first beta version of Siril 1.0, which was largely adopted and praised by users, we are releasing a second beta version, with number 0.99.6. It fixes important issues that were found in the previous release, 0.99.4, thanks to the kind feedback of our community. It has already been tested by many users and should work in most cases. Remember this is a beta version, but we consider it already better than the previous stable version, the 0.
Siril 0.99.4, available here, has introduced a lot of new features. In this post, we have listed the highlighted ones.
32-bit native # The most important and especially the most awaited change is the switch to native 32-bit floating point for all calculations. The default FITS format is now of type TFLOAT. The files are therefore twice as large in size as before and the memory used is also twice as large.
We think it is time, time to release this new version for beta testing.
Since the last stable version, the 0.9.12, more that 1400 commits were pushed to our repository, more than 66 000 new lines of code were added. A lot of new developers helped us in optimization, new features and bug fixes. It is for sure our biggest improvement to the code of Siril.
This is why, unlike we used to do, we’ve decided to publish a beta version for the three most common platforms.

Siril 0.9.10 has been released and brings its load of new features and improvements. It provides a new comet registration method, astrometry solving, previewing for processing functions, and new commands available for scripts. Windows support has been improved, in particular for special characters in file names. We also have moved to a gitlab source and issue control system to facilitate interaction with users and developers. See other news in the release notes(https://free-astro.
SiriL has moved to a new collaborative programming infrastructure hosted by Gitlab. The new URL is: https://gitlab.com/free-astro/siril On the end-user side, we also replaced our old bug submission form by the one from Gitlab.
SIRILIC # (Siril Image Converter) is a software for preparing acquisition files (raw, Offset, Flat and Dark) for processing with SiriL software.
It does three things:
Structuring the SiriL working directory into sub-folders Convert Raw, Offset, Dark or Flat files into SiriL sequence Automatically generate the SiriL script according to the files present and the options SIRILOT # The Sirilic version V0.36 provides an additional tool: Sirilot
It’s the contraction of “SiriL + Lot”.
A new OS X installer, packaged by a Siril user, is now available for the 0.9.9 version. The great news of this package is that the set of DSLR scripts is now embeded as it was already done for the Windows version. Moreover, it is now possible for the user to uninstall the application very easily and properly from his computer.

You may want to use Siril scripts to automatically pre-process your images at the end of the nightly sequence with KSTARS / INDI / EKOS. Or, you also may want to download the pre-processed, registered and stacked file and not all the RAW files in the case of a remote control observatory ?
Below is described the detailed procedure that was established after an exchange with Jasem, the main developer of EKOS :
It is possible to use scripts to pre-process the new images automatically for example at the end of the nightly sequence. You can now have your pre-processed files ready and immediately start the interesting part of the process. 😉 There is standard script you can use directly or if you have very specific needs you can modify them to make your own.
