De Vaucouleurs Atlas Description:

NGC 1411 is interesting because it is clearly nonbarred, yet it has well-differentiated structure in the form of a series of weak lenses. The (l) recognized in the classification refers to the prominent, intermediate-sized lens ; this is also the feature undoubtedly recognized as the ``(r)" in the RC3 type of SA(r)0-:. In the center, there is a small lens -like feature, while the outer disk also has a moderately sharp edge. In a luminosity profile, the edges of these features correspond to slight changes in the slope - none is really a ``plateau" as in the formal definition of a lens . Also, the interpretation of any of these features as ``inner" or ``outer" is ambiguous in this case, because the galaxy has no bar to guide us.
