Description

Captured on February 18 and 20.
Fortunately the sky cleared a bit and I could capture 2 hours of lum and 1hr colour

NGC 4395 is a low surface brightness spiral galaxy with a halo that is about 8′ in diameter.
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. The central black hole has a mass of "only" 300,000 Sun masses, which would make it a so-called "intermediate-mass black hole".
