Here is Sh2-88 with
            Sh2-87 just below at the very bottom. This is in Cygnus and is
            rarely imaged. The dark nebula just below it is LDN88 and LND87.
            Two bright spots of nebulosity appear just under Sh2-88. The
            entire background in Cygnus is filled with dim red nebulosity.
