它没有多少可见尘埃，表明是个低尘埃透镜星系，但也有可能当从上往下看时会发现螺旋状的结构。

Its lack of a visible dust lane indicates that it is a low-dust lenticular galaxy, although it is still possible that a view from on top would reveal spiral structure.

球对称梯度折射率微球透镜具有体积小、光路短、外形易加工、使用易调整，且无螺旋光线、像差小等优越性能。

The spherical gradient refractive index micro-lens with small volume and short optical path can be easily shaped and conveniently adjusted, and has no spiral rays and low spherical aberration.
