NGC 4395

[petevasey]

NGC4395 is quite a large Seyfert galaxy in Canes Venatici just on the border with Coma Berenices.  Large in the sky, but actually a dwarf galaxy 'only' 14 million light years away. Thought to have an unusually small black hole at its core, so of particular interest to astronomers.  At mag 10.2 it would seem to be fairly bright, but it is very diffuse with a surface brightness of only 15.4. Consequently a bit of a challenge to imagers.  Rather disturbed but classified as SBm, a galaxy with one single spiral arm. It also appears to me to be slightly barred. I first imaged this in April 2009 but only monochrome. A very poor season this year, but a long clear night was forecast for 7th March so I decided to revisit this interesting galaxy with this reasonably satisfying result. QSI683 on RC10 with SX AO unit. Luminance 18 x 10 minutes, RGB each 7 x 10 minutes, all binned 2x2.

Cheers,

Peter

Don’t think that I’ve seen images of this one before. Nice image too. This one could make a good visual challenge object for tonight in Pencelli if the clouds play ball.

Like Paul I don't believe I have ever seen this one done before, a very fine capture you have made of it too.

Superb and very sympathetically processed.  Great work Pete

New to me too, Peter, and an interesting galaxy.
