LDN 9999 Lynds Dark Nebula, also known as Barnard 427. Its about the size of the moon at 28'X28'.

This is a dark nebula in the shape of a "(>) less than sign" pointing to the right. It is just to the left "north" and a bit closer to the upper bright blue star. It is listed as an opacity of 4 on a scale of (1-6=darkest). There are stars visible in the nebula most likely behind it.
