Astrial Stage Disc - Aurora Borealis & Taiga. The "astronomical" disk is Northern Lights, or the northern lights. The background disk is taiga trees.
The discs work with Sega Toys Flux, Sega Toys Original and Sega Toys Classic, i.e. with all devices currently offered (2019: Flux and Original) and in the past (Classic)
The Astrial company scenic disk is a set of two disks - the main disk, with the main image, and the background disk, creating the main environment in the form of a horizon. Background disks are trees, mountains, telescopes, etc. When the Homestar planetarium rotation function is enabled, the main disk rotates while the background disk remains stationary. It's like lying on a beach among palm trees and watching the sky: the stars are flowing across the sky and the palm trees remain in place.
