Southern Galaxies Now In Starbase

There are new image sets available on Insight Observatory's Starbase for downloading! Franck Jobard co-owner of Deep-Sky Chile and Insight Observatory's affiliate remote telescope, ATEO-3 captured around 8 hours of luminance image data of galaxies NGC 1365 and NGC 1316-17-18 located in the southern constellation, Fornax. The image data was acquired over November and December of 2019. ATEO-3 is a 12.5" f/9 Quasar Ritchey Chretien, that is available for image requests on our Educational and Public Image Request forms as well as image sets for subscribing to in Starbase. Between gathering data for Insight Observatory's educational programs, Franck is currently in the process of capturing many hours of red, green and blue image data through the 12" RC. This data combined will make for excellent color image processing of the galaxies.

NGC 1365 is barred spiral galaxy in the Fornax cluster. Within the larger long bar stretching across the center of the galaxy appears to be a smaller bar that comprises the core, with an apparent size of about 50″ × 40″. This second bar is more prominent in infrared images of the central region of the galaxy, and likely arises from a combination of dynamical instabilities of stellar orbits in the region, along with gravity, density waves, and the overall rotation of the disc. The inner bar structure likely rotates as a whole more rapidly than the larger long bar, creating the diagonal shape seen in images.

NGC 1316-17-18 imaged on ATEO-3, 12.5" f/9 Quasar Ritchey Chretien - 8 hours of image data acquired by Franck Jobard and processed by Utkarsh Mishra.

NGC 1316 is a lenticular galaxy about 60 million light-years away in the constellation Fornax It is a radio galaxy and at 1400 MHz is the fourth-brightest radio source in the sky.

NGC 1317 (also known as NGC 1318) is barred spiral galaxy in constellation Fornax, in the Fornax cluster. It was discovered by Julius Schmidt on January 19, 1865. It appears to be interacting with much larger NGC 1316, but the uncertainty of distance and scales of tidal distortions make this uncertain.
