New CCD images show additional emission-line objects close to R Coronae Australis in the Corona Australis cloud. Two faint knots, strong in forbidden S II, are seen against the receding CO flow associated with R CrA. They are closely aligned with HH 104 A,B and R CrA and have thus been labeled HH 104 C,D. The position angle corresponds to that of the transient spike described by Hartigan and Graham (1987). HH 104 C,D lie on the edge of a diffuse patch of nebulosity, strongest in H-alpha. It is suggested that this is illuminated by light scattered from R CrA in the direction of the receding CO flow. The emission-line star 1-100 observed by Hartigan and Graham has a variable spectrum. There is a forbidden S II knot 17 arc sec W, 9 arcsec S of this star. A faint 19th magnitude emission-line star is identified. A change in the morphology of the HH 100 reflection nebula between 1973 and 1983 is noted.
