Description

The Cygnus Loop spectacular Supernova remnant with includes both the Eastern & Western Veil Nebula.  Taken during one of those nights with occasional wispy clouds that sometimes cover & sometimes reveal the target.  My solution was to shoot short exposures of 30 secs and reject any that were cloud affected. This seemed to work. I took 2 hours of exposures 174,  I excepted, the other 66 were cloud affected. All unguided.
I also understand (maybe incorrectly) that Pixinsight weights light frames during WBPP stacking & Integration in favour of those least affected. 
If I had used longer, say 3 min exposures I think the seeing would have been averaged over that time and more integration time would have been rejected.
It also helps that the Samyang lens I used at f2.8 supports short exposures.
