Description: This is one of the brightest non-Messier galaxies. Overview doesn't bare much, only the brightest parts are visible. The core is quite small, elongated and bright. There are brighter areas on the both ends of central bar: the southern one is a bit brighter and sharper. Spiral arms are difficult, but they are detectable with averted vision at 244x. Actually just inner arms are visible in these conditions.

Description: Galaksilla diffuusi ydin, joka ei juuri erotunut sitä ympäröivästä halosta. Ellipsi pohjois-etelä suunnassa. Näkyi heikosti koska transparency oli surkea.
