I have been experimenting and trying to get everything set up still so much to do...lots of little things..failed inverter, mount not doing exactly what I expect but I have managed about 6.5 hours all up and I am sorry I cant tell you the exact spread but I limited exposures to 2 minutes for everything.
Gain was around 240 for everything really but I cant be specific cause I still have to make a system to record all this better.
I probably should look at this again tomorrow but as I have been playing with this all day in photoshop and gimp I post it before the thing wears out
And looking at it here shows up problems which for some reason I don't seem to pick up on when looking on the lappy
