JA I am getting just so excited about what may be achieved with short exposures....I wonder just how many subs you can stack in Deep Sky Stacker...I think it spat the dummy when I tried 750 once but that could be the computer...anyways I am confident at 500...so 500 at 5 seconds seems like a starting point ...and I am going to go all 7 filters RBG so as to get good coloured stars...RBG just for star colour maybe...so much to think about....selecting the good subs seems an area to address...star count probably does not really indicate quality..I wonder...in the past I looked at each sub and decided...I suppose that is the best way...mmmm 500 subs by 7 filters thats 3500 say 10 seconds to judge but then there is the time to go to the next ... A long time but that is what I will need to do.
