Luka, I experiment with my DSLR settings. I set ISO at 800 for brighter objects like 47 Tuc and M42, but for fainter objects, I go for 1600.
I have done 5 mins at 1600, but they are very noisy (sensor running at 30c) and darks were not that useful.
I have experimented at around 3 mins at 1600. I found that for fainter (mag 7 or there abouts) DSOs, that will get histograms around the middle or just off to the left (2/5-3/5 of the histogram), but that's still quiet noisy (sensor around 20-23c). I will need to shoot matching darks to see if they can be toned down a bit more.
I think I will stick to this setting as the cooler months set in and see how I go.
On the other hand, DIY cooler for the DSLR....
