Description

This took several nights, fairly dim one but surprisingly large in visual diameter.

NGC 4395 is a low surface brightness spiral galaxy with a halo that is about 8′ in diameter. It has several wide areas of greater brightness running northwest to southeast. The one furthest southeast is the brightest. Three of the patches have their own NGC numbers: 4401, 4400, and 4399 running east to west.[3] The nucleus of NGC 4395 is active and the galaxy is classified as a Seyfert. It is notable for containing one of the smallest supermassive black hole with an accurately-determined mass.[4] The central black hole has a mass of "only" 300,000 Sun masses,[5] which would make it a so-called "intermediate-mass black hole".
