KStars 2.8.0 is released for Windows, MacOS, and Linux



Here comes another KStars release: v2.8.0 For Windows, MacOS, and Linux.

This is a minor bugfix release to increase stability of KStars on all supported platforms. Nevertheless, there were few significant updates:

video
  • Default NGC/IC catalog is now replaced by OpenNGC project. Christian Dersch compiled this catalog from OpenNGC. KStars now include more objects with accurate positions!

  • Lots of C++11/C++14 code migration work by GSoC 2017 student Csaba Kert├ęsz. This also included memory management clean-up, usage of smart pointers, valgrind suppression file and other fixes.

  • Adding support to selection of telescopes from Ekos equipment profile directly. This facilitates having different profiles when utilizing different telescopes on the same mount.
  • Michael Fulbright, KStars & INDI latest developer,  added the ability to have a scheduled refocus every N minutes during a capture sequence. Michael also added dither size in pixels and dither timeout to UI.
Many small bugs were fixed, thanks to our users who are making use of KDE Bug Tracking facilities effectively.

KStars 2.7.9 Released for Linux, Mac, Windows, and Android!

A new release of KStars is out! v2.7.9 is now available for Linux, Mac, and Windows. At the same time, we released an update to KStars Lite for Android.

This is mostly a bugfix release where we concentrated on fixing bugs as reported by our users. But that didn't stop us from creating new tools that were long requested by the community, including the Mount Control tool that facilitates motion and GOTO commands with a simple interface.

On the other hand, KStars GSoC 2017 project started with lots under the hood work taking place. Csaba went full throttle with migrating the C++ code to modern C++14 standards while updating the build process to be stricter, more secure, and efficient. The whole code base was formatted and countless warnings resolved. Furthermore, several enhancements were made to decrease memory usage and increase performance of tools such as Observation Planner.

For KStars Lite on Android, it now supports Automatic Mode where you can identify stars, planets, and constellations simply by pointing the phone toward the sky and looking at the live Sky Map within the App. Significant performance gains were made in FITS files that support WCS data. Since processing WCS is very CPU intensive, loading WCS data is now performed on demand. This is especially important for embedded devices where resources are limited.

Robert Lancaster implemented automatic download of Astrometry.net index files directly from the GUI. No longer the user have to go and hunt for index files, calculate FOVs for different equipment...etc. With the updated system, all the required index files are highlighted automatically by Ekos, and all you have to do is to click and download them!

Special thanks to all those who made this release possible. Outstanding work from KDE's Craft team, led by Hannah Von Reth, for making this great tool that enables KStars to reach users across all major platforms.

KStars 2.7.7 Released for Linux, Mac, and Windows!

The New What's Interesting Tool
I'm glad to announce the release of KStars 2.7.7 for Linux, Mac, and Windows!

In this release, Robert Lancaster dedicated a lot of time to improving KStars What's Interesting Tool (WIT). It is now significantly improved and offers a rich educational experience to explore the heavens! Users can now explore many naked eye and deep sky objects, in addition to addon catalogs offered by KStars such as the Sharpless Catalog.

Users wishing to have more fine control on what objects to observe and/or image should be using the Observation Planner that enable filtering of objects with custom constraints and limits. For casual users looking to find out what's interesting tonight, then this tool is the optimal choice.

Whether you're simply viewing the sky unaided with your eye or using binoculars/telescopes, find out which objects are available and how to locate them in the night sky.

The WIT fetches images and information on the objects and interest and can even fetch information from online sources like Wikipedia.

Mac Canon users will be glad to know the new release now enables them to fully control their DSLRs under OSX. Furthermore, the Mac release includes support for ZWO ASI cameras. We hope to add support for QHY for Mac in the next release.

Access to thousands of images like this

While KStars includes downloadable addons for images that appears in the detail dialog, John Sadler did a fantastic job of compiling images for over 18,000 NGC/IC objects!! These images are now available as downlodable addons, and now you can enjoy images of thousands of objects right within KStars. A small update to the Observation Planner enabled support for viewing images in there as well to help you plan what to observe and image ahead.



A few fixes were made to the Ekos Guide module to detect timeout in image captures and to take appropriate actions before giving up. Also, dithering failure does not necessary lead to autoguiding process failure. This behavior is now controlled by the user. By default, the autoguide process shall proceed even if dithering fails for whatever reason.


Finally, I added SkySafari support to INDI and now SkySafari users can enjoy using their app & KStars simultaneously to control their equipment without resorting to exotic hacks.

KStars 2.7.6 for Windows & OSX released

I am glad to announce the release of KStars 2.7.6 release for Windows & OSX. Linux users using the official PPA can install the latest release as well.

In this release, we introduce the Ekos Mount Modelling tool developed by Robert Lancaster. It's currently in Beta now and we would appreciate any feedback. The tool enables you to build a comprehensive mount model if supported by your mount. Any mount that improves its internal pointing model after a SYNC command is applicable. Furthermore, INDI mounts that supports INDI Alignment Subsystem (EQMod, Nexstarevo, Synscan..etc) are also applicable.


Along with the advanced mount modelling tool comes the new Solution Results plot in the Align Module. It displays the quality of your GOTO after each solve and it can help you to identify if there are issues with your mount or the quality of the image..etc.


You can zoom, pan, and drag to explore the plot in details. Annotation for the quality of each GOTO is available on mouse over.

Ekos Polar Alignment Assistant tool also received a few bug fixes from the community feedback. Most users were able to achieve impressive results using the this easy to use Polar Alignment tool.

While Ekos is designed for ease of use, it can be intimidating for new users unfamiliar with the architecture of Ekos/INDI on several operation systems. Therefore, a new Ekos Profile Wizard is now available to guide the users to setting up their equipment for the first time in Ekos across several operating systems and connection topologies.


With INDI v1.4.1+, figuring out which port to use for your mount & focuser is now trivial across Linux & OSX. INDI automatically scans ports on your system and can even automatically connect to all potential available ports as well until a successful connection is established.


Last, but not least, KStars' NEO (Near-Earth-Object) data query from NASA's JPL is now properly working again thanks to our newest KStars developer Valentin Boettcher. Valentin (aka Hiro) is only 18 years old but is quite brilliant and experienced with KDE/Qt development environment. Welcome abroad!

How to get 100 million stars in KStars

USNO NOMAD star catalog which contains ~100 million stars has been available in KStars for many years, but it appears many KStars users do not know how to get the catalog up and running.

The primary problem is its sheer size (1.4 GB) which tends to fail when being downloaded via KStars Download New Data tool. So here is a quick guide on how to obtain this catalog.

USNO NOMAD requires Tycho-2 catalog to be installed first. It is a relatively smaller download at only 32MB and can be safely installed using the Download New Data tool. Using the keyboard, click Ctrl + N to bring up the dialog, or go to Data → Download.


Navigate to Tycho-2 and click Install.


Wait until Tycho-2 is downloaded and installed. Now download the USNO NOMAD Catalog. Please either use a download manager to download the file, or use wget from the console. To use wget, open a console and type:

wget https://files.kde.org/edu/kstars/download.kde.org/kstars/USNO-NOMAD-1e8-1.0.tar.gz

Alternatively, you might want to checkout the mirror list first to download the files from a mirror close to you. After downloading the file, extract it and copy USNO-NOMAD-1e8.dat to ~/.local/share/kstars

If you are using console:

tar -xzf USNO-NOMAD-1e8-1.0.tar.gz
cp USNO-NOMAD-1e8.dat ~/.local/share/kstars

Now restart KStars, and go to Settings → Configure KStars. You'll see the Star Catalogs density slider, move it up and click Apply. You can control how many stars KStars draw on the screen, the more stars, the more resources it would take to render them, so adjust the slider carefully.




And if all goes well, you should have millions of stars on in your KStars Sky Map, enjoy!

KStars 2.7.5 is released for MacOS and Windows

I'm very excited to announce the release of KStars 2.7.5 for MacOS and Windows!

This is the first official KStars release for MacOS 10.11+, and while we made sure to test it thoroughly, please treat it as a beta release and report any bugs to the KDE bug tracking website.



KStars for MacOS supports all the features of the Linux KStars release, including Ekos and INDI. It comes ready with astrometry.net support, xplanet, and ability to download and install General Star Catalog (GSC) data used for CCD Simulator stars.

Most INDI drivers are imported with the exception of few Linux-specific drivers; we are investigating different approaches to improve INDI 3rd party drivers support under OSX. This release would not have been possible if not for the tireless efforts of KStars developers and INDI forums members.

Specifically, I'd like to thank the following volunteers for their significant contribution to the MacOS release:

  • Robert Lancaster: KStars latest developer and chief driver of the MacOS release. Robert greatly improved the usability and cross-platform capabilities of KStars while adding several very exciting and useful features to both KStars and Ekos.
  • Stephane Lucas: Initiated the longest (110+ pages) INDI thread Ekos for OS X that resulted in this release. Stephane carried out extensive testing and suggestions for Ekos Scheduler and aided in the KStars OSX Port.
  • Jamie Smith: Developed script to automate building of KStars using Craft, CMake, and XCode methods in addition to automating DMG builds.
Many INDI forums users also helped in testing this release, so I'd like to extend my thanks to all our users.

Along with the Mac OS release, a new KStars for Windows 64bit release is also available for download. You can download both release from KStars website.

KStars 2.7.4 for Windows is released!

Glad to announce the release of KStars v2.7.4 for Windows 64bit. This version is built a more recent Qt (5.8) and the latest KF5 frameworks for Windows bringing more features and stability.


This release brings in many bugs fixes, enhancements for limited-resources devices, and improvements, especially to KStars premier astrophotography tool: Ekos. Windows users would be glad to learn that they can now use offline astrometry solver in Windows, thanks to the efforts of the ANSVR Local Astrometry.net solver. The ANSVR mimics the astrometry.net online server on your local computer; thus the internet not required for any astrometry queries.

After installing the ANSVR server and downloading the appropriate index files for your setup, you can simply change the API URL to use the ANSVR server as illustrated below:



In Ekos align module, keep the solver type to Online so it would use the local ANSVR server for all astrometry queries. Then you can use the align module as you would normally do. This release also features the Ekos Polar Alignment Assistant tool, a very easy to use spot-on tool to polar align your mount.

Clear skies!
