The Corona Australis Molecular Cloud is a dusty nebula with both reflection and absorption components. This image here has a combined exposure of nearly 4 hours of data, shot under very good sky conditions in Mersing, Malaysia. NGC 6723, an ostensibly adjacent globular cluster (in fact much farther away from Earth than the nebula), is also visible here.

Shot with FSQ85 and SBIG ST8300M, tracked with Losmandy G11 Gemini 2
