Would it be possible to measure the radial velocity of stars with large exoplanets using amateur equipment?

Radial velocity is a measure of an object's motion towards or away from an observer. In astronomy, it is often used to measure the speed at which stars or other celestial objects are moving towards or away from Earth.
Radial velocity can be measured with amateur equipment by using a spectrograph, which separates the light from an object into its component wavelengths. By analyzing the Doppler shift of these wavelengths, the radial velocity of the object can be determined.
Yes, amateur equipment can measure radial velocity with a high degree of accuracy. However, it is important to note that the accuracy of the measurement depends on the quality of the equipment and the skill of the observer.
Amateur equipment can measure the radial velocity of a variety of celestial objects, including stars, planets, and even some galaxies. However, the accuracy of the measurement may vary depending on the distance and brightness of the object.
Radial velocity data is used in astronomy to study the motion and dynamics of celestial objects. It can provide information about the mass, orbit, and other physical properties of stars and planets, and can also help in the search for exoplanets and other astronomical phenomena.
