I'm not sure what you mean by without a break. You can add images taken over multiple nights or all taken at once. It doesn't matter but every time you readout the camera you add noise to the image so less readouts means less overall noise. This has to be offset against the potential loss of a long exposure from poor tracking, airplanes etc. I use 5 to 10 min subs as my compromise. Others use longer depending on their ability to guide etc.
