IC 4634 is a Planetary Nebula in the Ophiuchus constellation. IC 4634 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 visual magnitude of 10.9, IC 4634 is visible with the help of a telescope having an aperture of 6 inches (150mm) or more.

The image below is a photograph of IC 4634 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).
