RCW 104 in HOO

 

 

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)
