Thanks all.
I am suprised at the Mag my system can reach. During dark of moon I intend to try for fainter.

Yes. The "flashing dots". I think they are cosmic ray(radiation) strikes. On deeper images I combine images so they are hidden by averaging/addition etc..
On single images they can not be hidden and as part of an animation appear to flash. The "dust thingy" is a ray that hit at an angle.

As I usually take only one dark for these images they can effect all in the sequence when subtracted. I am slowly building a master dark.
