The Iris Nebula in Cepheus - NGC7023
Imaged from Nova Scotia, Summer, 2014 and 2021
The Iris nebula is a cloud of dust, brightly illuminated by the blue light of nearby stars. Areas not directly illuminated appear as a dusty veil. Denser portions of the dust cloud appear black and blot out the light from stars lying in the background. The nebula is located approximately 1,300 light years from Earth.
