CodeTalker chart generator from Ephemeris Service and Star Catalogs

CodeTalker, the chart generator program from Ephemeris Service and Star Catalogs offers dynamic tracking of celestial objects, aligning with your telescope's specific settings for optimal viewing. Available under GNU GPL v3.0, it includes a manual for easy setup.

In a recent development, a new software tool has been launched that allows astronomers to seamlessly integrate data from JPL Horizons with stars cataloged in GAIA DR3. Created to address specific challenges in observing faint moons and swiftly moving asteroids termed "fasteroids" by its creator—the software is designed to generate precise star charts deep enough to capture these elusive celestial bodies.

The creator emphasized the necessity for a tool that could accurately track fasteroids, which move several arcseconds per minute, making them difficult to observe with standard software. The software adjusts the position of celestial objects based on the user's specific geographic coordinates—latitude, longitude, and elevation—to enhance accuracy.

One of the standout features of this innovative tool is the "Update" button. This functionality allows users to refresh their observational data in real time. It proves especially useful in the field, where astronomers need to continually update their position to track fasteroids from the moment they are oriented to the time they successfully spot their target. This feature underlines the software's commitment to providing astronomers with the tools they need to follow rapidly moving objects in the night sky effectively.
