The galaxy shows you only dimmed nuclei by using of scopes, actually very fine two arms are coiled up in east-west direction. You can barely detect two lumps sticked to the nuclei in this image.
You can see M58 with M59 and M60 in low powered field of view, M58 is the most striking and brightest in the trio.
