SUMMARY

The discussion focuses on converting angles from a tri-axis accelerometer mounted on a telescope into right ascension/declination (ra/dec) or altitude/azimuth (alt/az) coordinate systems. It is established that if the accelerometer is mounted correctly, the alt-az coordinates can be derived directly. The conversion to ra/dec is feasible but requires consideration of the Earth's movement, which affects these coordinates over time. Resources such as the SEDS website and the book "Astronomy with Your Pocket Calculator" are recommended for further assistance.

PREREQUISITES
  • Understanding of tri-axis accelerometer functionality
  • Knowledge of celestial coordinate systems (ra/dec and alt/az)
  • Basic principles of telescope mounting and alignment
  • Familiarity with astronomical calculations and conversions
NEXT STEPS
  • Research the process of converting alt-az coordinates to ra/dec
  • Explore the use of software tools for astronomical calculations
  • Study the effects of Earth's rotation on celestial coordinates
  • Read "Astronomy with Your Pocket Calculator" for practical examples
USEFUL FOR

Astronomy enthusiasts, telescope operators, and anyone involved in celestial navigation or astrophotography will benefit from this discussion.

Hi !

I have mounted a tri-axis accelerometer on a telescope which gives me angles for x,y & z axis, is there a method to convert these angles to the ra/dec or alt/az coordinate systems.

Any help would be aprreciated

Welcome to PF.
Depending on how you mounted it - you should get alt-az directly, converting to Ra/Dec isn't hard (remember that for a given Ra/Dec the alt-az constanlty changes as the Earth moves)

Try here http://seds.org/~spider/spider/ScholarX/coords.html or if you can find a copy there is the famous "astronomy with your pocket calculator"
