Star Adventurer: Many short or few long exposures ?

I continue with my Star Adventurer experiments how to get the most out of it.

I can notice when I taking 120 seconds exposures with my Star Adventurer mount and the 150 mm camera lens I sometimes get elonged stars. And with that long exposures also the brighter stars oversaturate.

How will my equipment perform if I take more and shorter exposurers, can my Canon 6D handle that? It has relative low readout noise at higher ISO settings but limited dynamic then.

Here I have done two tests to compare:

At least in this case I feel the camera can handle the shorter exposure and still have good dynamics.

I live close to a big city, but I have found two places out in the east close to the coast where I have a relative dark sky. With my small ST I can easy go out there and doing astrophotographing.

Almost all my earlier AP have been done with a very lightpolluted sky.
