| Notes: | NGC 7023 is the reflection nebula around the 7.4 magnitude star SAO 19158, centered in this image. Some catalogues list NGC 7023 as an open cluster ... 'Star Clusters', by Brent Archinal and Steven Hynes, says "This is a reflection nebula with the star cluster Collinder 427 involved on its west side". In the broader field around NGC 7023 is a very dusty region, well shown in in this wide field color image by Dean Jacobsen |
