Description

SH2-29,31 & 32 :SH2-29, 30 & 30 form a HII ionized hydrogen zone containing many other objects like reflection nebulae (which are also nurseries of stars like NGC 6559, IC 4684 & IC 4685), dark molecular clouds or dark nebulae like B 91 & B 303 and LDN 221, 230 and 212 as well as a Minkowski 1-41 planetary nebula.This region is located in Saggitarius just to the west and contiguous to M8 "the Lagoon".Presented here in 2 versions: one in HaL- SIIHaR-GOII-BOIII and the other in SHO which makes it possible to better distinguish the details of the nebulae.
