NGC 2997 is a face-on unbarred spiral galaxy about 40 million light-years away in the faint southern constellation of Antlia. It was discovered March 4, 1793 by German-born astronomer William Herschel. J. L. E. Dreyer described it as, "a remarkable object, very faint, very large, very gradually then very suddenly bright middle and 4 arcsec nucleus. This is the brightest galaxy of the NGC 2997 group of galaxies, and was featured on the cover of the first edition of Galactic Dynamics by James Binney and Scott Tremaine.This is a grand-design galaxy with a symmetrical, two-armed form. The morphological classification of NGC 2997 is SAB(rs)c, indicating a weakly-barred spiral galaxy (SAB) with an incomplete ring around the bar (rs) and loosely-wound spiral arms (c).
CHI-1 belongs to, Telescope Live. It is a Planewave CDK24, a 61-cm telescope with Corrected Dall Kirkham optical
design, situated in the Rio Hurtado Valley, Chile. It is equipped with a set of
Astrodon astrophotography filters as well as Sloan photometry filters and it's,
therefore, an excellent choice for both scientific applications and
astrophotography of deep-sky objects.
