Expert technicians make giant telescope's mirror

[JustWonderingHowToDo]

What is the hexagonal structure at 4:14? Is this ceramic and what is it's purpose, why are there grooves in there.

I've spent all my time under a microscope instead of telescopes. I want a good balanced telescope where I can put Saturn in full view, but also view galaxies. What size of mirror should I get and which size of eye-pieces? I understand smaller eye-pieces for Saturn and larger eye-pieces for galaxies, but you need a good size mirror to see each clearly. Just curious. And thanks in advance.

@drunkasssteve I guess your comments a year old, but to reply: Celestron or Meade are great manufacturers (depends on your budget), around 6-8" is a good size mirror. I prefer an SCT type, and yes depending on if your just doing visual vs. photography, there are pros/cons to each type. Typically you'll need around 500x to see details on Saturn, the same for galaxies, except you won't see much colour with your (human) eyes, need a CCD camera for that.

those expert technicians sure looked a lot like undergrads to me.
