Thanks for the comments, I'll look at rejecting bad frames and suggestions. Interesting that 580 frames took much less time than I experienced. I'll have to check my PC out as its a reasonable spec though I did find apps were not using the NVIDIA GPU by default which may be relevant. Jerry

I was pleased to see the stacking feature and watched the youtube video. I tried to stack a set of files I'd stacked using DSS and gave up after about 20 hours of waiting. There were about 700 plus bias as well which processed in DSS in about 90 mins (I dont remember the exact time). I ran a few quick and dirty tests using Affinity and time varied roughly linearly with number of files up to 250 lights (46 min) then at 350 shot up (151 mins). If I use a tracking mount I wont need as many as 750 or I could just use DSS for the stack in that case but it would be nice to use Affinity start to finish. Jerry
