Haven't been around for quite a few months as we haven't had a full clear night now in the UK since last October and I was starting to feel a bit despondent about imaging. However, I'm starting to see a few possible clear nights appearing on the horizon so am doing a bit of processing to make way for new data.
Was playing around with DBE settings and wondered what other people thought on placement options when nebulosity in the field is quite full. In the screen shot image below, I have tried 3 different models. The first one on the far left has small placement points (size 15) placed strategically into the darkest areas of the image only, the second one has larger sample points (size 40) using sample generation with those that fall on significant nebulosity removed and the last one has the same largest sample points but placed around the edges of the image though still avoiding the nebulosity.
As you can see, there are subtle difference - the first one has more nebulosity with less contrast whilst the last one reverses this difference. I am heading towards the middle version but am interested in what you think?
