Observational astronomy is a delightful subject for both beginners and serious students of astronomy. It can be a fun hobby. There are several different methods and research techniques that you can use in observational astronomy. You can rely on different observation tools like telescopes, micrometer, spectrograph and photoelectric photometry.
If you want to enhance your knowledge of observational astronomy, you can also learn more about absolute photometry, spectroscopy, infrared telescopes, x-ray astronomy and radio astronomy. The methods of observational astronomy are mainly based on the concept of discovering how far an object is and observing wavelengths across the electromagnetic spectrum.
