Ayers Rock hey, your in astro heaven I'd expect !! I gotta see that rock one day ?
Re Subs, seeing you have been using iso 1600, id suggest to keep on 1600, as know the higher iso the more noise, particularly in summer months, tho if you drop to iso 800 then you'll need to add to even longer subs to gather the same light signal, - problem - the trade off is the longer the sub time the more noise again
So, iso 1600 and plenty of them - say atleast 15 - 20.
Are you doing "in-camera-darks" what a slow painstaking caper that is, valuable imaging time ticking away, if you wish to add Darks, then can do them on a cloudy night .
Hope this helps ..
