Alt: -63.49° Az: 167.74° Direction: South-South-East

NGC 3620 is a Barred Spiral Galaxy in the Chamaeleon constellation. NGC 3620 is situated close to the southern celestial pole and, as such, it is easilty visible for most part of the year from the southern hemisphere. Given its B magnitude of 15.9, NGC 3620 is visible only through long exposure photography.

The image below is a photograph of NGC 3620 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).
