NGC 7023 is a reflection nebula which lies 1300 light-years away in Cepheus. It is 3˚27' southwest of B-class, magnitude 3.2 Alfirk. Burnham described the object as "large faint nebulosity, 18' diameter, complex structure, bright and dark masses and outer filaments".

Today's APOD of the Iris Nebula is from Jimmy Walker. The image shows plenty of the "bright and dark masses" Burnham mentioned.
