NGC 5745 is a Galaxy Triplet in the Libra constellation. NGC 5745 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 14, NGC 5745 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.

The image below is a photograph of NGC 5745 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).
