IC 308 - Lenticular Galaxy in Perseus
IC 308 is a Lenticular Galaxy in the Perseus constellation. IC 308 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 16.5, IC 308 is visible only through long exposure photography.
The image below is a photograph of IC 308 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).
