Within this Section, we aim to foster an interest in spectroscopy from your backyard. Whether you are a beginner or a skilled observer, or if you seek to make genuine scientific contributions, there is something here for you.

Moving forward, it is expected that enthusiasts will apply the knowledge and skills acquired here to further their understanding of the subject and, when ready, begin contributing to science. The steps to follow are:

  1. Understanding spectroscopy theory
  2. Purchasing a transmission blazed grating
  3. Setting up a telescope and DSLR or astro camera
  4. Configuring a tracking telescope setup
  5. Practising taking spectra repeatedly using easy-to-analyse A-type stars
  6. Downloading the software for analysing spectra
  7. Practising and becoming proficient with the software
  8. Progressing to more advanced projects

Remember, practice and understanding are key to mastering this subject.
