Thank you very much for all the encouragement.
Setting I presume you mean b/w balance iif so on auto...maybe
and I think this was more like 50 minutes at 200 iso...as I said I have been playing with them and files have breed like rabbits ... I will post some others only to encourage others who may be thinking of having a go not to wait until they get a flash scope.. I recon I could do this using a $250 eq scope and mount ..I whatched the guide star in the 70mm guide scope on and off during captures and it wandered a fair bit really without really showing up as star trails... the same wander if only using 400fl would have been disaster.
Here are some crops from larger widefields .
