I really wanted to capture this object. In Stellarium it appears quite bright, but in reality it's very 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 in the southeast. Three of these regions have their own NGC numbers: 4401, 4400, and 4399, from east to west. The nucleus of NGC 4395 is active, classifying it as a Seyfert galaxy. 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."

This object is interesting and quite large, measuring 13.2' × 11.0'.
The surface brightness is low, but the result is there and well done!
If another 6 hours or so are added, I think it will be super.

Let's see about another 6 hours, it's very bright here, the Milky Way isn't visible.
