M-77 is a small barred spiral galaxy.   The f3.3 image just barely shows the bar.  The central core is very bright, so it is difficult to capture the spiral structure without over exposing the central regions.   I really need to go back and try an image it at f10. 

You should be able to glimpse it as a fuzzy star in a 90 mm scope because of the concentrated bright central core area.   The stars of the constellation Cetus are relative dim.  If you can see them from your location, then you have a chance of finding M-77 without a computer guided scope.   Use the magnitude 4.1 star, Delta Cet as a starting point.    M 77 is about 1 deg from this star.   NGC 1055 is about two magnitudes dimmer than M-77.  At magnitude 11.4, it probably wont be visible in a 90 mm scope.
