https://github.com/cyschneck/star-chart-spherical-projection - 2.0.0 - Code Refactor with RA Fix
⭐ Major Release and Fixes⭐
Update and overhaul to all functions which includes an important fix for calculating Right Ascension and calculating Proper Motion
Standardize Function and Variable Names
- plotStereographicProjection() -> plotstereographicprojection()
- finalPositionOfStars() -> final_position()
- starPositionOverTime() -> positionovertime()
- predictPoleStar() -> predictpolestar()
- newStar() -> addnewstar()
Data
Data processing and web scrapping has been moved to a new repo that is updated monthly - All 505 IAU Named Stars from the IAU WSGN Star Catalog - Data collected from new repo: iau-star-names
Backend
- Convert setup.py to pyproject.toml
- Replace format to f-strings
- Update pytest.yml and setup codecov and dependabot
- Update README.md with 2025 examples

https://github.com/cyschneck/star-chart-spherical-projection - 1.6.0 - starPositionOverTime, predictPoleStar, new stars
⭐ New functions for plotting and predicting a star's position over time and at a specific year ⭐
New functions are still in beta functionality and will continue to be tested and expanded
starPositionOverTime() and plotStarPositionOverTime()
Return a single star's position over time
starPositionOverTime(builtInStarName=None,
newStar=None,
startYearSince2000=None,
endYearSince2000=None,
incrementYear=5,
isPrecessionIncluded=True,
save_to_csv=None)
And associated function to plot the star's declination and right ascension position over time
plotStarPositionOverTime(builtInStarName=None,
newStar=None,
startYearSince2000=None,
endYearSince2000=None,
incrementYear=10,
isPrecessionIncluded=True,
DecOrRA="D",
showPlot=True,
showYearMarker=True,
fig_plot_title=None,
fig_plot_color="C0",
figsize_n=12,
figsize_dpi=100,
save_plot_name=None)
For example, Vega's Declination with Precession:
star_chart_spherical_projection.plotStarPositionOverTime(builtInStarName="Vega",
newStar=None,
startYearSince2000=-15000,
endYearSince2000=15000,
isPrecessionIncluded=True,
incrementYear=5,
DecOrRA="D")
And Vega's declination without Precession:
star_chart_spherical_projection.plotStarPositionOverTime(builtInStarName="Vega",
newStar=None,
startYearSince2000=-15000,
endYearSince2000=15000,
isPrecessionIncluded=False,
incrementYear=5,
DecOrRA="D")
predictPoleStar()
Return the North/South Pole star for a given year since 2000 while taking into account precession
predictPoleStar(yearSince2000=0, northOrSouth="North")
New Built-In Stars
Alkaphrah, Alkarab, Alkes, Almaaz, Alnasl, Alfirk, Algedi, Algenib, Algorab, Aljanah, Alkalurops, Absolutno, Achird, Acubens, Adhafera, Adhil, Ain, Alafar, Ainalrami, Alasia, Albaldah, Albali

https://github.com/cyschneck/star-chart-spherical-projection - Add New Stars and Save Output to CSV
Add a New Star to Existing Data with newStar Class - Users can now add new stars (fix to Issue 1) - Two methods to add new stars to a plotStereographicProjection() and finalPositionOfStars() 1. newStar(starName=None, ra=None, dec=None, properMotionSpeed=None, properMotionAngle=None, magnitudeVisual=None) - A new star with a proper motion speed and a proper motion angle 3. newStar(starName=None, ra=None, dec=None, properMotionSpeedRA=None, properMotionSpeedDec=None, magnitudeVisual=None) - A new star with the proper motion speed for right ascension and declination
userListOfStars -> builtInStars
- Renamed argument userListOfStars to builtInStars
New argument to plotStereographicProjection() - userDefinedStars: List of newStar objects of stars the user has added - onlyDisplayUserStars: Only display the stars defined by the users (userDefinedStars)
New argument to finalPositionOfStars() - userDefinedStars: List of newStar objects of stars the user has added - onlyDisplayUserStars: Only display the stars defined by the users (userDefinedStars) - savetocsv: CSV filename and location to save final star positions with headers ["Star Name", "Right Ascension (HH.MM.SS)", "Declination (DD.SS)"]
