Finally some clear nights - managed to get 14x10mins of Ha and OIII to add to my previous NGC6188 LRGB data. Unfortuantely I selected the wrong reference image so framing was not quite what I wanted but luckily not a complete write off.
Here's 31x5mins LRGB with 14x10mins Ha and OIII added. I'm quite amazed how much detail the Ha brings out.
