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.
Thanks for the comments Larry and Ross. I'm going to have another go at it tonight with the right reference frame an might get the blue data again as I suspect the focus wasn't quite right last time.
Looking good Peter.
I've been getting some Ha on this one last couple of nights, but only get a few hours between the trees. Fingers crossed for more decent weather for sure!
Great renditions Peter. I like the traditional RGB over the narrowband, but the target is well suited to both palettes. Stars look a little crunchy. Not sure if you use DDP to stretch your data but it can certainly assist it managing stellar profiles. Looking forward to more.
