Astro Tutorial #1.8: Science behind telescopes - field curvature, coma corrector and light paths

Old version. Watch:    • Astro Tutorial #1.8: Science behind t...   for enhanced audio and a coffee free version!

Hey folks!
This video it’s time for some science!

Are all light beams from the same star?
