This huge galaxy gives up a lot of detail in the eyepiece, but on the video screen begins to look like a long exposure photograph, showing off much of the same detail seen on deep CCD images.

M106's inclination is similar to that of M31, and it shows off many of the same details as that much closer galaxy (M106 is about 25,000,000 light years distant). Carl Seyfert originally classed M106 as one of his "peculiar galaxies," but it's rarely mentioned with the other Seyfert galaxies today despite being a strong radio emitter.
