Thanks all, much appreciate the comments.
Peter W, you always seem to get better prom detail but I suspect this is because I do not do a run for the prominences and I choose to brighten those up. Having the extra aperture would help you too. Yes I did see proms of course but there was nothing really large. Mind you I have another run to process yet and there might be something in there.
Peter (Poita) we had heaps of cloud but this was not the issue for me, I had to hurry to get data and the etalon settings were not optimal.
John, I don't think that is atmosphere. I think it is more likely processing artifacts myself, but it may be atmosphere.
Vivek, under the image you will find all the details of the image including equipment. Basically I processed 6 panels (I actually wanted 12 or so) with 700 frames in each panel. Then I do a combine in photoshop which is not perfect but I need advice on a mosaic program that will even out the frames.
