Iridium satellites are great to photograph especially if they are bright, around magnitude -1 or better.
This one was rather high in the sky at my location located in South East Queensland. 30 seconds was rather a long exposure and there slight star trails. I wasn't sure of capture window so decided to go for a longer exposure time. The duration was around 5 seconds.
