NGC 7773 is a Spiral Galaxy in the Pegasus constellation. NGC 7773 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 14.5, NGC 7773 is visible with the help of a telescope having an aperture of 20 inches (500mm) or more.

The image below is a photograph of NGC 7773 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).
