I'm wanting to get to 5 seconds  There must be a standard bench mark for total photons/min or something similar that would assist...... |

https://www.youtube.com/watch?v=3RH93UvP358 YouTube Vid deals with that very issue Wes. It's mainly aimed at CMOS/CCD imaging but you can apply the CMOS principals to your DLSR. The nuts & bolts part is towards the end if you can sit through it. I had to watch it a couple of times to get my head around the theory but it's well worth it. DR Robin Glover is the speaker. You could also google "optimum sub exposure length/ astrophotography' or similar, there's plenty of info out there.
