If the galaxy is oriented edge-on, it appears cigar-shaped, sometimes with a dark dust lane
That abrupt drop in brightness marks the position of a dark dust lane
between two of the spiral arms on the galaxy's near side.
In the 1840s astronomer Sir John Herschel observed a dark streak running across the galaxy, now known to be a thick dust lane
Seen visually there is probably nothing more impressive than an edge-on galaxy complete with a rippled dust lane
filling the field of view of a large telescope, and NGC 4565 is one of the most impressive in this respect.

It is a beautiful spiral galaxy, displaying a dust lane
stretching in a north-south direction, and gradually brightening to a small but very bright nucleus.
Melong, another student from Red Dust Lane
, entered the Shanghai Teacher's College with his score actually lower than Lihua's because of his worker family background.
The Andromeda Galaxy (M31) showed a dust lane
, M15 was resolved to the core, and he even spotted Neptune's moon, Triton.
Look for the dark dust lane
that divides it nearly in half.
One of the most obvious features in images of the galaxy is the dark dust lane
running along its length.
The galaxy is tilted just enough that the core peeks over the dust lane
, so it looks like a bright star right there at the center.
That marks the innermost edge of the dark dust lane
that's so prominent in photographs.
