Excellent. you can tell the exposure was long if you look closely at the short star trails. I don't mind them at all but if you wanted to get rid of them you could raise the ISO up from base but too high will give noisy sky, dark featureless areas is where noise lives.
Thanks for your comment. In fact I went out to shoot some night scenes with low ISO/long exposure to get clean images and maybe some movement/light traces. While I could have pushed ISO for that particular shot I kind of like the cleanliness of the image.
