Through various examples of instruments, we will illustrate the specific technical designs, operational strategies and instrumental techniques developed for ground-based solar optical telescopes. This will address questions like:
- How do solar observing techniques differ from nighttime observations of the deep sky?
- What are the key advantages and difficulties that can be exploited or need to be mitigated when observing our nearest (bright!) star?
You will see that over the years, solar astronomers invented many clever approaches, from observing-site selection to unique focal equipment.
