HNSKY

Hallo Northern Sky (HNSKY) offers an extraordinary planetarium experience for astronomy enthusiasts. The latest version, 3.2.2, brings a wealth of features that make this program a standout in its category. Notably, HNSKY is a full-featured planetarium program that supports Windows XP, Vista, 7, 8, 10, and even the newer Windows 11 operating systems, making it versatile for many users.

The extensive database is impressive, with 30,000 deep sky objects and the TYCHO2++ 4.5 million star database providing star visibility up to magnitude 12.5. For those seeking even greater detail, downloading the GSC 1.2 or the USNO UCAC4 allows stars to be displayed up to magnitude 16. This makes HNSKY an invaluable tool for both amateur stargazers and more experienced astronomers.

Using the program is straightforward due to its two main executable files: hnsky.exe, and hnsky_themes.exe. These files are essential for running the application and customizing its appearance to user preferences. Han Kleijn, the developer of HNSKY, has put significant effort into ensuring that the software is not only powerful but also user-friendly.

HNSKY is classified under the Education category, specifically as a Science Tool. This classification is fitting as the program serves as an excellent resource for learning about celestial objects and navigating the night sky. The license of the program is Freeware, making it accessible to a wide audience without any cost barriers. Users can simply download it and start exploring the galaxy.

Past versions such as 3.2, 3.1, and 3.0 laid the groundwork for the current iteration, building on each previous version's capabilities. These continued improvements underscore the program's evolution and the commitment to offering a comprehensive astronomy tool.

One of the highlights is its ability to control almost any telescope through the ASCOM interface program. This feature can significantly enhance the observational experience by integrating digital star maps directly with physical equipment.

Downloading of additional DSS images and the ability to blend them in at the correct size and orientation provide users with an enriched visual experience. The integrated deep sky help file further aids in understanding and navigating through the rich star data available.

• Extensive star and deep sky object databases
• Free to download and use
• Supports a wide range of Windows OS versions
• Ability to control telescopes via ASCOM interface
• Integrated support for additional DSS images
• Multilingual with 21 non-English menus
