Amazing job!
The star is XPS foam that was cut on a hot wire table with a template cut from 
med draftboard. Once cut, the foam was coated with Rosco foam coat and metallic pigments.
The ring that sits on top of the star is med draftboard. The engraving was filled with a metallic spray paint. Here is a link to how I do that: Driver Panel, Out of Control!
The border rings around the engraved ring are med draftboard with some rub and buff for color.
The bezel around the dome was 3d printed in abs plastic, then hit with rub and buff.
The dome itself is med clear acrylic that was cut and engraved flat, then formed with a blow mold die. Here is a thread where I have a video of that process: Gold Inlay on formed acrylic dome. Success!
The settings were standard settings, I think I used the HD setting for the engrave on the acrylic.
Hope this answers anything you were curious about.

Haha, great! Thanks a ton!
Absolutely amazing. Thanks for sharing. As a high school Art teacher (17 years) and huge GoT fan, I got super excited to show my students that the opening credits were made on the very machine we just bought for our program.
