Broadening not due to origin in our galaxy as telescope has ability to look at one piece, like one star, of galaxy at a time. Broadening due to range of velocities of stars from within that piece.

However, there is a shift in doppler depending on where the telescope looks which is as you specified above.

If the telescope is looking at a distant galaxy, then what you say is correct. Just a clarification.
