[[IC 1297]] is a [[planetary nebula]] of apparent magnitude 10.7, which appears as a green-hued roundish object in higher-powered amateur instruments.{{refn|name=Griffiths 2012 p132}} The nebula surrounds the variable star RU Coronae Australis, which has an average apparent magnitude of 12.9{{sfn|Moore, ''Data Book''|2000|pp=367–368}} and is a WC class [[Wolf–Rayet star]].{{sfn|SIMBAD RU Coronae Australis}} IC 1297 is small, at only 7 arcseconds in diameter; it has been described as "a square with rounded edges" in the eyepiece, elongated in the north–south direction.{{sfn|Bakich|2010|p=270}} Descriptions of its color encompass blue, blue-tinged green, and green-tinged blue.{{sfn|Bakich|2010|p=270}}

Corona Australis' location near the Milky Way means that galaxies are uncommonly seen. [[NGC 6768]] is a magnitude 11.2 object 35′ south of IC 1297. It is made up of two galaxies merging,{{sfn|Streicher|2008|pp=135–139}} one of which is an elongated [[elliptical galaxy]] of classification E4 and the other a [[lenticular galaxy]] of classification S0.{{sfn|NASA/IPAC NGC 6768}} [[IC 4808]] is a galaxy of apparent magnitude 12.9 located on the border of Corona Australis with the neighbouring constellation of Telescopium and 3.9 degrees west-southwest of [[Beta Sagittarii]]. However, amateur telescopes will only show a suggestion of its spiral structure. It is 1.9 arcminutes by 0.8 arcminutes. The central area of the galaxy does appear brighter in an amateur instrument, which shows it to be tilted northeast–southwest.{{sfn|Bakich Podcast|18 August 2011}}

Southeast of Theta and southwest of Eta lies the [[open cluster]] [[ESO 281-SC24]], which is composed of the yellow 9th magnitude star GSC 7914 178 1 and five 10th to 11th magnitude stars.{{sfn|Streicher|2008|pp=135–139}} Halfway between Theta Coronae Australis and [[Theta Scorpii]] is the dense globular cluster [[NGC 6541]]. Described as between magnitude 6.3{{refn|name=O'Meara 2002 pp273++}} and magnitude 6.6,{{sfn|Moore|Rees|2011|p=413}} it is visible in binoculars and small telescopes. Around 22000 light years away, it is around 100 light years in diameter.{{refn|name=O'Meara 2002 pp273++}} It is estimated to be around 14 billion years old.{{refn|name=O'Meara 2011 p322}} NGC 6541 appears 13.1 arcminutes in diameter and is somewhat resolvable in large amateur instruments; a 12-inch telescope reveals approximately 100 stars but the core remains unresolved.{{sfn|Bakich Podcast|5 July 2012}}
