My focal length is what I think allows me to image to 30minute subs without problems... I was considering trying 45min exposures this weekend at barambah just to see if it will do it..
Even staying at 5 minute exposures, you're images would benefit a lot just by doubling or tripling your total exposures.. Ie. instead of 7 x 300sec images, go for 14 to say, 30x 5 min... it will result in a smoother overall image.. and from dark skies, i find more exposures generally makes colour balance easier to sort out in processing...
More data is the key to imaging (or at least, as far as I've figured thus far) Judging by my early attempts of M8, one that is 10x30sec (5 minutes total) and one that is 8x300sec (40 minutes total), then comparing it to my recent M8 image, 18x20minute shots + 24x5min shots (8 hours total)
I do understand though... I've been organising a target list for barambah for the past 3 weeks.. It started out with 12 targets I planned to image over the course of the 3 nights... Slowly but surely, I've narrowed this list down to just 4 targets... I have also made this list so Im essentially imaging target 1 untill it goes too low to image, by which time, target two is just getting high enough to image, by the time target 2 hits the meridian, target 3 will be high enough to start imaging, and by the time target 3 gets too low, target 4 will be high enough to image untill dawn. I intend to run this schedule for the 3 nights straight... and should get 7hrs per target... Hopefully this will quench my thirst for colour imaging for a while, as when I get home, it will be straight back into the narrowband imaging.

All the best for Barambah Alex. Wish I was there, but looking forward to just chilling with the family this weekend. I'll expect you and the others to suck down a beer while the Floyd is playing at some time though in my place though.....
