Yes! The entire dust cloud is red. In a simple RGB image it's impossible to "see" what light is coming from reflection and what is coming from extended red emission (ERE), but spectroscopically that is easy to determine.Can you see any red light in the APOD?APOD Robot wrote:
Central filaments of the reflection nebula glow with a faint reddish photoluminescence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula contains complex carbon molecules known as PAHs.
