Hello, I am a fourth-year Interior Design Student. For my Final Major Project I am hoping to design an observatory and lecture space designed to encourage more people to engage with stargazing. I am currently researching the best location for this type of building. Naturally the darker the site the better it is for observing but I would like to know if there is a limit or maximum recommended level to the lighting radiance level or lux level of the surrounding area. Attached is a photo of a lighting radiance key that may help to determine the answer to my question as it breaks the radiance levels down into sections. I would be grateful for any opinions, knowledge or information relating to this J Thank you in advance for your help Larissa
