About this image

Since I couldn’t see anything on the screen, and couldn’t work out the camera orientation (not being one of the smart wallahs), I only got half of the shark - but at least it was the “business end”! It is a mix of 15, 20 and 30 mins exposures, at 3200 ISO….(oh yes). Bit of an experiment there! The auto guiding was running (of course), but since the object was very near the zenith, the prog didn’t have a lot of work to do, and the tracking adjustment trace was essentially clean.
