Exposure Time

So im starting to work my way through this maze of information. I have the SVBONY 503 80mm with flatenner. So acodring to my calculations my F number is 5.6. So Is there a difference between a 3 minute exposure at lets say 800iso or 3x1minute exposures. Im shooting with the dslr and I realize that the longer exposure will introduce noise and lets say tracking is perfect. I hope this is making sense, basically why would I chose a 2 minute exposure over 2x1minute exposures.

Cheers Legends
