NGC 635 is a Spiral Galaxy in the Cetus constellation. NGC 635 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its B magnitude of 15.55, NGC 635 is visible only through long exposure photography.

The image below is a photograph of NGC 635 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).
