NGC 6729 Corona Australis Nebula (LRGB)
NGC 6729 is a wonderful astronomical object that consists of both a reflection nebula and an emission nebula.
NGC 6729 is also known as Caldwell 68 and is a nebula of the Corona Australis Molecular Cloud, located about 400 light-years away in the constellation Corona Australis.
I used the following software: Astro Pixel Processor for stacking and PixInsight for processing (Gradient Correction, BlurXT, SPCC, SCNR, ColorSaturation, NoiseXT, ...).
