So it is - I have my Astroplanner plan based on NGC numbers. Thanks for the comments. 1 min seemed like a long exposure when I was doing 10 secs pre-guiding!!!

Another lovely shot with great detail. What you are managing to get out of the DSI is incredible. You only have two options from now on. Either 5 min guided subs or get a cooled CCD camera.
Great shot again. We will have to set up side by side and have a shoot out.
