RCW 74 Dark Nebulas

How do I write this up. I saw an interesting shape inside the Coal Sack and one Nebula RCW 74 ,So what do I get what will it look like. This came out nothing like I expected I thought I was going to get a B/W over all image but a bright nebula at the bottom. This was rotated but the focuser body hit the scope base plate so I just went with what I had rather than full proper rotation.
You can imagine my very first morning of data and seeing all this colour I thought what went wrong. None the less I kept on going what I get is what I get. This started out as Ha Sii Oiii but Oiii was a blank shot of stars. This is stacked Foraxx Ha Sii this has blown me away, There is colour in space where you least expect it.



You cant miss the shape Right side middle in the Coal Sack.
