RCW is an oval shaped emission nebula in the Constellation Norma created by the Wolf Rayet star HD 147419


The region is blanketed in HAlpha emission. In an effort to pick up OIII emissions I integrated nearly three times as much data in OIII as in Ha to produce this image


Total integration 19 hours collected over 5 nights

15 hours in OIII and 4 hours in H alpha ( 10 minute subs)
