I really wanted to capture this object. In Stellarium it appears quite bright, but in reality it's extremely faint—just not suitable for my skies.

NGC 4395 is a low surface brightness spiral galaxy with a halo about 8′ in diameter. It contains several broad, brighter regions aligned from northwest to southeast, with the brightest one located in the southeast. Three of these regions have their own NGC numbers: 4401, 4400, and 4399, arranged from east to west. The nucleus of NGC 4395 is active, classifying the galaxy as a Seyfert. Notably, it hosts one of the smallest supermassive black holes with a precisely determined mass. The central black hole has a mass of "only" 300,000 solar masses, making it what is called an "intermediate-mass black hole."
