NGC 249 - HII Ionized region in Tucana
NGC 249 is a HII Ionized region in the Tucana constellation. NGC 249 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its B magnitude of 13.8, NGC 249 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 249 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).
