Figure 6: Another photo showcasing the field of view size of the 7-Dimensional Telescope. In addition to the six full moons shown in Figure 4, the field of view of the James Webb Telescope (based on the NIRCAM camera) is also compared. The field of view of the 7-Dimensional Telescope is approximately 1,000 times larger than that of the James Webb Telescope's imaging instrument.

Figure 8-a: Color image synthesized from images taken at wavelengths of 370 nm, 500 nm, and 650 nm, corresponding to blue, green, and red. The green (500 nm) represents the intense ultraviolet from a star with a temperature of 120,000 degrees Celsius at the center and the hot gas of the nebula reacting with oxygen. The reddish areas in the periphery show light emitted from cooler hydrogen and nitrogen gas.

Figure 8-b: Color composite image of at 400 nm (blue), 525 nm (green), and 675 nm (red) wavelengths. In contrast to Figure 7-a, only light from the sulfur (S) element is visible in the 675 nm wavelength, highlighted in red.

Figure 8-c: Color composite image at 425 nm (blue), 600 nm (green), and 700 nm (red) wavelengths. This wavelength range has minimal emission from elements, resulting in a very dark appearance, but faint light from helium (He) is visible.

Figure 8-d: Color composite image at 450 nm (blue), 625 nm (green), and 725 nm (red) wavelengths. The green represents light from oxygen near 630 nm, while the red shows light emitted by argon (Ar) at 713.6 nm.

Figure 9: Pseudo-color image of the Trifid Nebula captured by the 7-Dimensional Telescope. The red color (650 nm) is due to hydrogen ionized by the intense light of newly born stars, while the blue color is a result of nearby interstellar clouds reflecting starlight. The bright points in the red and blue nebulae are newly born, massive stars.
