Description

LDN1587/Sh2-261 (Sharpless 261) also known as Lower’s Nebula was discovered in 1939. The Lowers (father and son) were amateur astronomers and found this nebula on one of their photographic plates taken in 1939. It is a faint region emitting predominately doubly ionized hydrogen, the nebula has an apparent diameter of about 50 arcminutes. There is no accurate measurement as to the distance of this nebula, although best estimation is about 3.300 light years.

This was processed between new and half moon phases  in HSO with 600s exposures.  21 Ha, 39 OIII, and 21 SII.
