Hi all.
Managed to get a little Ha on this last night just to finish it up.
While the cluster came out nicely, I think due to the reflective dust and entwined emission that surrounds this area, it appears rather stodgy in the area from the Ngc3324 through to the cluster. Sort of lacks depth, bit like a soup. No noise reduction applied but this area looks like it.
I used the Ha as a blend to the red channel to hi light and improve the colour about the main HII area.
Hard area to be happy with.
Still I do like the cluster's reflection!
Details are on the image page if you'd like to take a look...
