Yeah but you can't do much about light pollution so it's boring. With the telescope or the long lens you can learn how to deal with vibrations, drift, learn how to calibrate tracking, etc...
There are things you can do with physical+software filters, and bias frames in general, for wide astrophotography shots.
My point is you'll need a tracker with the long lens, worry about light pollution with a wide lens, and worry about neither with a telescope because human eyes aren't limited to ISO6400 and can stack in real time.
