With this image I tried to detect the known tidal stellar streams around the galactic halo of Messier 63.

Because of skyglow here at my location it is very difficult to show the low surface brightness stellar streams. But still on the inverted image shown below the tidal stellar streams are suggested.

The "strip" visible from the above left corner to the down right corner is probably  a diffraction spike caused by  the star Alpha Canes Venatici which is located around 6 degrees away form Messier 63.
