I'm not sure about the 30secs good bad or otherwise using the 600 rule I probably could have expected 0.2sec of untracked exposure so this is 150x better then what I'm used to, if it was an 18mm star scape the same alignment and tracking would probably be good for 8mins, but didn't try it. Globby stars, not sure probably over processing trying to get to much I have included a single frame of each image to get some idea of the original capture.
