That is the beauty of F2.0 my lens is effectively like a small SCT with hyperstar so 30 seconds gets pretty deep and not too much noise but I might upgrade my camera to a modded one or 20mp with lower noise and if I nail polar alignment I should be able to do 60secs.

I also have a NEQ6 so I want to try to program that to do the mosaics automatically.
It get some pretty nice detail if nothing else Pixels are still really big at 8.445 micon so that is one reason I'd like to go for a Nikon D810a with its 36.8mp sensor

60s is REALLY not enough for this camera, it cleans up considerably better at the 120s mark at ISO1600. I have found that if I don't get above the read noise it is very bad. These were shot at 32º above horizon so also not very well placed.
