Yes i do, the difference is in a barred spiral some of the spirals have had a quicker spin speed than others and therefore the slower spirals have blocked the larger spirals creating usually 2 large spirals.

A normal spiral looks like the one in the picture, it has 2, 4 or 8 arms and is easily distinguishable from the barred spiral imo.

Though im also very interested in astrophysics, which may give me more knowledge about these things.
