The night preceeding my M3 and M5 efforts I managed a couple of widefield images of the constellations Bootes and Hercules using just the 450D with the stock 18-55mm lens focused at around 25mm focal length according to the EXIF data, using exposures of 120 seconds. So much easier at such a short focal length 🙂 These are both stacks of 18 frames.
It’s not at all easy to pick out the stars forming the asterisms themselves, with the exception of Arcturus which is pretty difficult to miss.
