Hi All, Having had to move to an apartment where I could not use my CPC 1100, I decided that I have to see what I could do with my NexStar SLT 102 (alt-az achromatic 102mm f6.47 refractor). Setting up on my narrow balcony was challenging and the altitude bearing was so loose that it almost moved from the weight of the Canon 700D. I could not see M31 in the estimated 3.5 magnitude sky so I did a two star alignment and used the live-view to focus on a bright star. I then took a 15 second exposure after slewing to M31 which allowed me to see that I had it in the field of view. After a few more 15 second exposures and playing with the motion controls I managed to get it centered. The resulting picture is from 39 subs of 30 seconds at ISO 1600, 9 flats. The images were stacked and stretched with Siril and then I played with the curves on Gimp, cropped and scaled. Not too unhappy.
Hi everyone, I'm pleased to share a good news with you. Indeed, thanks to Partha Bagchi (https://www.partha.com/) we are now able to provide you an .app file for OS X users. This is a good improvement because no Homebrew or Xcode are needed anymore. Also !! the app is 10% faster for stacking. You can download the app here. Enjoy !!
Hello, we are glad and proud to announce that a new version of Siril has just been released and is now available to all users: Siril 0.9.4. 1 - Presentation: Siril is meant to be Iris for Linux (sirI-L). It is an astronomical image processing tool, able to convert, pre-process images, help aligning them automatically or manually, stack them and enhance final images. 2 - How to install the release: Each new version is produced with several packages for most OS we handled. We try to build maximum of packages and cheer you to check if a package does exist for your OS at this page: http://free-astro.org/index.php/Siril:0.9.4 People on Ubuntu 16.04 or Linux Mint 18.XX can now download PPA repository in order to simply install last version of Siril: sudo add-apt-repository ppa:lock042/siril sudo apt-get update sudo apt-get install siril We've also decided in this version to produce standalone application AppImages for using Siril in many GNU/Linux distributions. However, it seems that the package does not work very well on all systems yet. Remember that Siril is a software for UNIX-like system, in consequence it does not work on Windows. 3 - New features: Siril 0.9.4 is a stability and minor improvements release: it contains several bug fixes and at least 10 improvements over to the previous version, Siril v0.9.3. Fixed issues with SER in generic processing function Fixed inability to open FITS when filename had parenthesis Fixed selecting new images did not update the number of selected images Fixed histogram sliders lag on OS-X Fixed message "Error in highest quality accepted for sequence processing....." during stack of %, even if quality data are computed Fixed sequence export to SER with unselected images Fixed global star alignment with angle close to 180deg Fixed undo cosmetic correction Fixed crash in peaker function Fixed aborting global star registration summary Fixed sequence list which was unreadable with dark GTK theme Fixed the update of the list of images Added support of internationalization: French, Dutch, Chinese, Italian, Arabic Option for logarithm scale in histogram transformation Add siril.desktop in archlinux Added support for exporting sequence in avi format Option to make a selection for global star registration in a smaller region Read commands from a file Option to follow star in registration Added support for resizing exported sequence Added support for reading and writing SER timestamps Added support for RGB alignment Added functionality to fix broken (0 framecount) SER files We sincerely hope you will enjoy using Siril and you will produce nice shots.

Hello, we are glad and proud to announce that a new version of Siril has just been released and is now available to all users: Siril 0.9.7. 1 - Presentation: Siril is (was ?) meant to be Iris for Linux (sirI-L), but is also now working on Windows (tested on 7, 8 and 10). It is an astronomical image processing tool, able to convert, pre-process images, help aligning them automatically or manually, stack them and enhance final images. 2 - How to install the release: Each new version is produced with several packages for most OS we handled. We try to build maximum of packages and cheer you to check if a package does exist for your OS at this page: https://free-astro.o...tle=Siril:0.9.7 A packages is available for all these systems: GNU/Linux (deb, rpm, appImage) OS X Windows 3 - New features: Siril 0.9.7 is a stability release: it contains several bug fixes and some improvements over to the previous version, Siril v0.9.6. The most important feature we implement in this new version is the new automatic registration algorithm. This algorithm uses a robust RANSAC routine that optimize the first search.
