There is great amount of galaxies in the Canes Venatici constellation, but NGC4395 spiral galaxy is for example rare catch. Probably due to its low surface brightness.

But today not about this galaxy, because the subexposures are still beeing collected. Apparently close to NGC4395 there is very remote world - SDSS J122645.33+332800.9 quasar with apparent visual magnitude 20.57mag. It is placed about 12 billion light years away.
