The Whirlpool Galaxy (Messier 51) is pretty easy to locate. I targeted Mizar and Alkaid, the last two stars in handle of the Big Dipper, with a TPO UltraWide 180 f/4.5 lens and M 51 appears comfortably within the frame. I tracked with a MoveShootMove rotator. Stacked 30 frames at f/4.5, 25s and ISO 1600 in Sequator and edited in stacked image in Photoshop and Luminar.
