Description

Original image: 30min integral RGB exposure of the starfield in the triangle of beta Cen, alpha Cen and alpha Cir, featuring many emission, reflective and dark nebulae and star clusters - captured remotely using Telescope #4 (Nikkor 200mm f/2, FLI Microline 16200) system of ChileScope observatory, also known as VST - a Very Small Telescope)) on Mar 28, 2023.

Revision B: 1h 30min integral Ha exposure of exactly the same area, captured remotely using Telescope #4 (Nikkor 200mm f/2, FLI Microline 16200) system of ChileScope observatory, also known as VST - a Very Small Telescope)) on Mar 28, 2023, with object annotations generated using PixInsignt.

Two main highlights in the original image are the immediate surroundings of alpha Cen:

and beta Cen as well:

showing many dark nebular surrounding both. The obvious color difference between these two extra bright stars adds to be beauty of the scene.
