NGC 855 is a Elliptical Galaxy in the Triangulum constellation. NGC 855 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its visual magnitude of 12.75, NGC 855 is visible with the help of a telescope having an aperture of 10 inches (250mm) or more.

The image below is a photograph of NGC 855 from the Digitized Sky Survey 2 (DSS2 - see the credits section) taken in the red channel. The area of sky represented in the image is 0.5000x0.5000 degrees (30.00x30.00 arcmins).
