I don't know exactly what is meant by "12-160-exposures" but I'm certain that no-one would take a 6 hour sub! 

Most stars would be saturated and it would be full of satellite trails, aircraft trails, cosmic ray hits etc.  In addition, any kind of equipment failure would threaten up to 6 hours of data.  How many objects can be continuously imaged for a 6 hour period anyway?

Another image says 57-hour exposure.  This clearly refers to the total exposure time.

That's what I thought, I think it must have been an error.  But his total was something like 18 hours, so all a bit confusing. However I know some-one who quite often does 1 hour subs.
