If you haven't seen it, you might like to read Ray's thread: http://www.iceinspace.com.au/forum/s...d.php?t=155908 on exposure times for the ASI1600. It might not be necessary to try for longer exposures, but perhaps more of them?

Thanks Chris, that's some interesting reading.
Looks like I am at my limit on exposure length in the red zone and can go shorter. Narrowband surprises me, 5.5 mins seemed too long for me specially in OIII, I tend to go for around Median 850ADU in SGP which is 4 mins subs in HA and SII but 3 mins on OIII.
I have only shot on Unity so far.....all this is very new to me.
