Is There a Formula for Calculating Star Altitude and Azimuth Over Time?

Click For Summary
SUMMARY

The discussion centers on calculating the altitude and azimuth of stars over time without converting to Right Ascension (RA) and Declination (DEC). The original poster seeks a formula to determine the positions of nine stars at a later time based on their current altitude and azimuth. While no specific formula is provided, a suggestion is made to explore software available at HNSKY, which may assist in this calculation.

PREREQUISITES
  • Understanding of celestial coordinates, specifically altitude and azimuth.
  • Familiarity with astronomical software tools, such as HNSKY.
  • Basic knowledge of star movement and celestial mechanics.
  • Experience with observational astronomy techniques.
NEXT STEPS
  • Research the algorithms used in HNSKY for star position calculations.
  • Explore celestial mechanics to understand star movement over time.
  • Learn about the mathematical relationships between altitude, azimuth, RA, and DEC.
  • Investigate other astronomical software that offers similar functionalities.
USEFUL FOR

Astronomers, astrophysics students, and amateur stargazers interested in calculating star positions without converting to RA and DEC.

Hi all.
I have a question.
Is there a way to calculate the altitude and azimuth of a star at a given time using as an input the altitude and azimuth of that star at an earlier time, without having to convert those coordinates to RA and DEC?
The problem is that I want to calculate the position (alt,az) of a nine stars a a later time when I know where the stars are right now. I don' want to calculate the RA and DEC of each star and then calculate back. I hope that there might a formula but I haven't found it yet.
Thank you for your help

hi there,

can't help on the formula, but there must be a way to do it as my telescope can do that :)

here's one site into that sort of thing, there maybe something there that can help you ?
