Spiral Galaxy M77 in Cetus
All galaxies are thought to harbor black holes in their centers.  Some black holes are larger than others.  M77 has a massive black hole,
which against intuition contributes to a bright galactic nucleus.  This is generated by large quantities of material falling into the black hole,
being superheated and accelerated, leading to powerful emission of radiation in the visible, radio, and X-ray frequencies.  This places M77
into the category of Seyfert Galaxies, which have “active galactic nuclei.�

At a distance of 45 million light years, M77 is one of the largest of Messier’s galaxies.  The faint outer arms extend out to a diameter of
170,000 light years.

This image combined 105 minutes of luminance, 30 minutes each of red and green and 15 minutes of blue exposures, mostly binned 2x2
but with 15 minutes of unbinned luminance.  An ST10XME camera was used through a Meade 12â€� LX200R and an AP reducer at the
Hidden Lake Observatory.
