This is another galaxy in the constellation Canes Venatici. The image is based on 180s exposures:
L 46, R 25, G 20, B 24
The galaxy is fairly dim (10.6). There is a lot of noise, I have stretched it a lot and clearly the SNR is pretty low. The trouble is, its April and the Astronomical Night is now getting pretty short. I can image between round 10 pm and 4 am.
Wikipedia: 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. 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".
