M77 (NGC1068) is a small spiral galaxy at 50 arc minutes ESE of delta Ceti.
The constellation of Cetus includes a number of galaxies, but most of which are very faint and generally unnoticeable.
The galaxy has a size of 7-by-6 arc minutes and 9th magnitude, and is one of the brightest in the constellation, distance is estimated about 47 million light years.
You can recognize the figure of an ellipse with only small scopes, but the galaxy has no evoluted spirals, so detailed structures do not come visible with larger telescopes.
M77 is one of the so-called Seyfert galaxies, which have strong radio sources.
